For example, you have some altcoin (in my case it's Metaverse ETP) and you expect it to grow. But in a weak market, this altcoin behaves like bull and you have the opportunity now to sell it and buy an asset that looks weak in the market (for example Qash, Tierion, Nem, Odyssey or Republic Protocol) in order to get the greatest possible profit. Or leave a strong asset and wait for its further growth. What do you think about this?
The main reason for diversification is because we don't know what will happen in the future. And when you ask, that means you need it. Indeed, trends do not have to be the same, but an altcoin can be intentionally pumped. So if you have done enough research, I think dividing on a few coins will be better for portfolio balance.
