You have not lost money till you sell. Hold on to the coins no matter what.
The ups and downs are part of the game. The big players buy your cheap coins when you get tired of waiting.
Last winter was a prime example of how it can turn around. Holding is always the best medicine.
I'm talking established coins and projects. Not the proliferation of eth based shitcoin tokens. Anyone holding a majority of these are going to go broke.
Loosing money by choosing the wrong coins because their project is going south,i can live with that.
Dealing with the market conditions,don't care it's part of the game.
The crypto ecosystem is nothing like the stock market.
You never know what's gone to happen to a coin. Delisted,scam,fraud,bad management etc.
It's like a boxing match, you have to watch your opponent and the referee, you never know which one is gone to punch you. Funny world the cryptos.
