Personal mantra in times when BTC forms new all time highs every day.
Stay calm.
Accumulate Alts on dips when price hits the big moving averages (50/100 on 4h/1d TF)
Hold some hand-picked nano cap shitters as moon bags. Don't touch them now. It's not their time yet.
Trading <<< HODL. Now is not the top.
BTC is for eternity and dark times.
Stay humble.
Don't short (unless you're scalping).
Focus on some good alts and don't get too distracted by crypto X. Have more of less coins and wait for 2x instead of having many coins waiting for 100x.
Buy low ("when there's blood in the streets, even if it's your own"), sell high (when you want to share screenshots of your portfolio).
It's a game. be aware you don't have the cheatcodes and you don't make the rules.
Not financial advice
