If I give you a suggestion which coin to buy, when is the right time to trade coins again, that's the wrong strategy in my opinion, the crypto market is unpredictable because prices go up and down still happen, As an investor, you should be able to find your own opportunities to invest your funds, make no mistake in making decisions, if you make the wrong decision you will receive a loss, the simple principle is that you buy when the price drops, and you sell when the price is at its peak or feels that you have made a small profit from the purchase price.
