because cryptocurrency prices are very unpredictable, so it's safe you have to buy them as fast as you can and what you wait for a long time, I suggest you buy coins now and don't wait too long
Buy crypto currencies that have good prospects right now, then wait until prices improve and profits are enough, then sell as soon as possible. Because the crypto price fluctuations are quite high, the time factor is crucial in achieving profit.
What are you going to wait for? The bull run time is coming soon. If you have the money that you can spend, spend it to the cryptocurrency. Invest in the best projects like EOS, Ethlend, Eidoo.
