For the most part, everyone in crypto is here for the profit. Don't kid yourself. If you talk to any seasoned investor about getting rich in this field, the plan is simple. Buy equal shares of the top 25 coins, 50 if you can afford it. One of them will hit and you'll be flush.
Going all in on one coin is financial suicide. Just imagine you went all in with ETH at $300. Then missed the top side.
We spread things out pretty well in the top 100 coins. We lose some, we gain some and every so often we get a hit like ETH at $400. Don't be greedy. Play within your means. And be prepared to be wiped out at any moment.
Crypto is not a game for the faint of heart. You need nerves of steel for this. Play long, play safe and enjoy.
