My biggest loss in crypto came from altcoin. And my biggest profit in crypto came from altcoin. New altcoins entering the market is high risk and high reward. Talk about cake, bake, ubix, woof, shiba Inu, "Luna", Matic, BNB in their earliest days, these gave people massive profit and some persons lost out too. You can't be wrong with BITCOIN as a store of value, it's the king of crypto.
This simply means that we altcoin movement is way more unpredictable than Bitcoin. Though at the current stage, Altcoins have more potential to give us a huge amount of profit, the risk involved is also unfathomable. If a person doesn't want too much risk but wanted to have an above-average profit, investing in Bitcoin is the best option. But if an investor doesn't care about the possible risk then I think altcoin is the best one since altcoin can really surge in a shorter period of time.
It is not an easy task to make profit from altcoins "consistently" thats the problem. I do not know if there is any situation that could be done any other way, but altocins are seasonal, which means that you can't make profit from them at all times. So all that "generating benefits to investors" things are also seasonable as well.
Depends on how informed you are in the altcoin industry. If you manage to be the first one in the line of investors then I think profit would pretty much be consistent with you.
