For me AVAX (avalanche) Is the coin i got good profit in this coin by investing 5 times.
First two times i got huge profits.
But after that not huge but that was also the good profit by holding same coin.
Or a single altcoin can sweep all of your funds in a single day.
This is the risk of investing altcoins it's more risky than investing in Bitcoin and you will never know what coin would give you profit that's why you have to risk on investing even if it means losing your funds. As long as you can afford what you lose you're still fine because that's what investment but make sure you know what you are doing or else it could end up badly.
A few people get lucky on investing with altcoins if they get profit but also there are unfortunate people who lost a lot after the investment.
Fortunately, many of us just earn those tokens in bounty campaigns. I have some altcoins that made up to $20K. It's a huge win and a bounty participant just worked for 4-6 weeks. Lucky for those who sold after that because some of these tokens never rise again after a bear market.
One token that I invested in was Cardano (ADA) when its price dipped to $0.02, I bought close to 17K ADA tokens. Sold them at $2.75. That's still a profit and bought back above $0.50 though so I'm at loss again.
