I do not see the point in buying and holding cheap altcoins in the hope that they will become much more expensive. Bought, 2-3 days and sold, that's my strategy.
You're right, but there are still risks. The main question is: How to avoid risks?
There is no way you can avoid the risk and see it as part of your investment plan. If you want to reduce the risk to the lowest level, you can choose some coins in the top 30 CMC because it is the safest option but the opportunity to make a lot of profit will be very low. During this period you should have confidence in the coins you think have potential because the altcoin season is about to come back and there are already a lot of coins returning to the old ATH.
the profit in the top 30 is very high, and the risk is low, why do you mention that the top 30 in this season is difficult to get high profits?
Look at Ethereum having pumps, Cardano, and also Tron this project in top 30
