Plus those altcoins are pumping? Because Bitcoin is pumping. If Bitcoin crashes, I'm very confident that they will also crash and the crash will be heavier up to -90%.
Newbies in this market will learn their lessons by falling in love with altcoins soon.
Even altcoins pumped hard recent months, because Bitcoin triggered the market bull run, many of them are still -80 %, -90% of their all time highs. I believe this screenshot can help newbies to see risk of altcoins if they find this post.
But one thing you left out, you yourself said that bitcoin triggered the bull run and many altcoins are still at -90%, which means the chances of them being dumped or falling more is very low. So, buying altcoins now will not be as risky as when we are in the 2022 bear season. Also, look at what's been going on in the past few days, shiba is up 3x since the bottom, pepe is up 7x since the bottom...and many other altcoins.
We need to admit that during the bull season, altcoins will perform much better than bitcoin in terms of returns. But when the bear market begins, it's time to stay away from altcoins.
But these altcoins that just pumped hundreds of percent might now drop by 50% lol.
The point is altcoins are inhernetly extremely risky and extremely bad investments. And anyone can make a new altcoin so there is no way to know WHICH altcoins are going to pump. A few months from now there could be an entire new set of popular altcoins and the current ones could go down a lot from here on out.
To make the point more obvious. A lot of altcoins still haven't reached the local tops they hit a year ago on the market enthusiasm of bitcoin breaking out of the bear market the first few months of last year. So Bitcoin has 3x'd while many altcoins have gone down since then.
The investment strategy of buying altcoins is literally: "do you feel lucky today".
The chance of altcoins being dump is never "very low", as you say. The chance of altcoins dumping is always very high, even in bull markets. Because unlike Bitcoin, theres tons of altcoins to choose from. At any point some will dump and some will pump. Some will never go higher than they are today. No way to know which ones will be which. A few altcoins happened to just pump very hard, for some of them that very well might be as high as they go this market cycle, or ever. While others may 10x by end of the year. No way to know which will be which. Literally all it takes to replace any of them is for someone to make a funny sounding meme coin name and have it go viral and suddenly that's the new thing and all the altcoins that just pumped hard are yesterday's news.
