How Chains Handle Congestion Ethereum: Auction-style fees improved by EIP-1559 + Layer 2s that batch transactions. Solana & others: Higher throughput designs that aim for lower, more stable fees. Result: Same activity can cost $50+ on Ethereum L1 and cents on an L2#GasFees#Crypto
Why Fees Spike Blockchains have limited space in each block.
When many people try to transact at once NFT mints, market volatility, popular airdrops, demand exceeds supply. Users bid higher gas prices to get included first → fees spike and some transactions get stuck.

What Gas Fees Actually Are
Gas is the fee you pay to get a transaction processed on a blockchain.
Think of it like postage: more complex actions cost more “gas.” You set a gas price how much you’re willing to pay and a gas limit maximum you’re willing to spend. #GasFees#Crypto
High fees and slow transactions frustrate almost every crypto user.
This week I’ll explain simply:
• What gas fees actually are
• Why networks get congested
• How different chains handle it
• Practical ways to pay less
Starting Monday at 8 AM.

MVRV, SOPR, exchange flows, realized price, NUPL + combining multiple model families.
Single models almost always fail. Ensembles + strict out-of-sample testing + position sizing are what separate useful forecasts from noise.
X/Twitter sentiment, news NLP, Google Trends, funding rates, open interest.
These often lead price in the short term but are noisy and easily gamed. Best used as confirmation or early-warning signals rather than standalone forecasts.
Which alt-data source do you trust?
Random Forests, XGBoost, LSTMs, Transformers.
They can find non-linear patterns traditional models miss, but they overfit easily and struggle with distribution shifts. Feature engineering and walk-forward validation matter more than the algorithm itself.
Classical time-series models
ARIMA, SARIMA, GARCH, and variants. Great at capturing volatility clustering. Weak at regime shifts and long-term trends. Most pure ARIMA models break down once Bitcoin leaves a clear range.
Anyone still running forecasts?
Technical Analysis models
Moving averages, RSI, MACD, Bollinger Bands, support/resistance.They work better as regime filters than pure price predictors. In crypto the biggest edge usually comes from combining them with volume and higher-timeframe structure.
Starting tomorrow at 8 AM I’ll break down the main ways people try to forecast crypto prices:
1. Technical Analysis
2. Classical time-series
3. Machine Learning
4. Sentiment & alt-data
5. On-chain + ensembles
Smart contracts are powerful but unforgiving.
Bugs are permanent. Audits help but aren’t perfect.
User behavior (approvals, phishing) causes many losses.
Simple checklist:
Is the code verified? Who controls upgrades? How long has it been live?
#Crypto#Exchange
Reduce risk: approve only needed amounts and revoke old approvals; verify contracts on explorers; avoid links/signatures; choose time-locked, multi-sig protocols. Most losses come from phishing and unlimited approvals.
A good audit finds many issues and improves code quality.
It does not guarantee safety.
Audits are time-boxed, can miss novel attacks, and the code can still be upgraded or have admin keys. Treat “audited” as a positive signal, not a green light. #Crypto#Exchange
Most hacks exploit a few repeated problems:Reentrancy calling back into a contract before it finishes Broken access control anyone can call admin functions Logic errors and incorrect assumptions Unchecked external calls These are the patterns behind the majority of large losses.
A smart contract is code that runs on a blockchain and automatically executes when conditions are met. Once deployed, it usually can’t be changed.
“Code is law” means the contract does exactly what is written — including any bugs or backdoors. #Crypto#Exchange
Smart contracts power DeFi, NFTs, and most of crypto.
They also create some of the biggest risks.
This week I’ll cover:
• What they actually are
• Common ways they get hacked
• Audits and their limits
• Practical ways to stay safer
Starting Monday at 8 AM.
Beginner Pitfalls & Next Steps
Common mistakes:
• Treating one metric as a crystal ball
• Ignoring bots, incentives, and wash activity
• Comparing raw numbers across very different chains
Free places to start: Glassnode, Dune, DefiLlama, CryptoQuant.

Combining the Big Three
Strong signal example: Rising active addresses + rising TVL + exchange outflows = growing real usage and accumulation. Weak signal: Falling addresses + falling TVL + heavy inflows = declining interest and potential selling. Context always matters.#Crypto
Exchange Flows
Exchange inflows = coins moving onto exchanges (often sell pressure).
Exchange outflows = coins leaving exchanges often accumulation.
Large sustained outflows can be bullish. Sudden big inflows can signal upcoming selling. Best used with other metrics. #Crypto
