Altcoins are always about ambush attacks, it's sudden surges, and by the time you notice, it's already too late. Getting in means you're only halfway up the mountain or even at the peak; if you manage to get in, you might only eat a little before it peaks. Some might rise a bit more, but the risks keep increasing.

So, you need to set up an ambush in advance. If you set up an ambush, a problem arises: how do you determine that the point you are ambushing is relatively low? What if it drops by 50% or even more after you ambush?

This means you need to operate with coins you are familiar with. Altcoins can drop without a limit. Besides BNB and Bitcoin, which can provide a relatively good prediction of the bottom, predicting ETH's drop is very difficult. It can drop below 1400; SOL can also drop without a bottom, and other altcoins are even worse!

So, if you want to make money with altcoins, you need to first predict the bottom of Bitcoin, get in at the same time, and be prepared to add to your position at any moment. Once you make a profit, return the principal first and keep the profit as you like.
