I never bet to many money on cryptocurrencies. But i also made some huge losses. The most of them just because i dont want to sell and hold the coin, and now they are worthlesss. As example the ETHgas airdrop coin. Before the pump i buyed some for some dollars. On the peak i could sell it to one ethereum. But this time the ethereum blockchainw as totally overleaded so i could not make any transaction, and i think it hodl it because it will be worth a lot more.
