I like this sentence fragment "I did dabble with altcoins and learned soon after that it was a mistake, it wasn't slow". Currently, many altcoins seem to have reached the bottom of their market cycle and many still like to spin in altcoins during reversals.
Mostly people who dabbled in altcoins ended up having their same hands burnt. Altcoin investment is driven by the fact that early bitcoin investors are if still holding their coins, millionaires at the current price. They think that same price rise is coming up for altcoins, but this is a wrong assumption. Bitcoin is one of a kind and its success will not be replicated by any altcoin, whatever their vision might be.
Eventually these people understood their folly and moved away from cryptocurrency and not even bitcoin was touched by them. Those who have been in this community for long know what potential bitcoin has and hence it is the only coin to buy.
I do not encourage people to invest in altcoins because of the risks involved, but what do you say about ETH? Because it is also an altcoin or BNB...and many other altcoins have also been bringing huge profits to many investments. I really don't know what the future holds for those altcoins, but so far it's clear that if people invested in them from the early days, the returns they received were no less than those who invested bitcoin early. Altcoins are very risky , many people have lost money because of it but not all, mate. Many people have become rich thanks to altcoins and even shitcoins like doge.
