@Deepreeti786 Off-course Bitcoin but saving is not enough, if you are rich then you can invest in Bitcoin to stay rich but if you are trying to become rich then you need to find best performing alt coin to become rich. Bitcoin is too big now to give you 1x/2x return.
@CryptoPatel I agree but it depends whether you are trading or investing. For trading, you need to see the chart pattern, location and price action but for investment, you need to include moving average along with long term trend. Always buy near moving average with stop loss.
