My alternate coin experience was quite good enough because all my altcoins comes from airdrop and i hodl it until know and im happy with 10000 usd as profit as of the moment. Hopefully ACC,HAT,and etc will be pump again. have mostly positive experience with altcoins. There has been some on which I lost a little bit of money but few excellent ones like Cardano and Verge bought just before the price jumps have more than made up for it.
