For me the problem is:

Why are people buying at High prices, but you didnt buy when the price was low??

It doesnt matter if they are cryptos, or stocks. If you buy at high prices, you will have a crash 90% of the cases.

So, If I were new here, i will wait to see a big correction, or at least dont put all my money at this prices maybe 30%.

If you buy at low prices, It doesnt matter if they go down again, and again. Holding for long term is the best (and relaxed) strategy
