I will tell you not to keep the alt coins for long. Because the alt coins almost always go down. Something pump that has been seen to rise. If you ever go to the market and research a few coins, you will find the original answer. Keep large coins such as BTC, ETH or BNB for a long time. Then more profit can come
Usually people who have been in the cryptocurrency world for a long time will not keep existing altcoins for long, they are more likely to buy or store BTC and Ethereum, even though they buy in amounts not up to one coin, but there are also many people who make purchases of altcoins, but they don't. held too long after the purchase, they will use the short term investment towards the altcoin.
Not so my friend. It all depends on how the strategy will be used even though the assets they have are Bitcoin and Ethereum. If the current price has reached the profit target, then choosing not to keep or choosing to sell can also be the right strategy to do.
