I think this drop is completely normal in the crypto market. We have seen the market have a very high gain in April, clearly, the market needs a small correction to be able to continue growing.
There have always been drops in the price of cryptocurrencies and it is so normal. Overall since the beginning of this year, most currencies have started very well, and as you above said April was the best month for cryptocurrencies, but as you know everything can not be as expected, everybody knows that the price would decrease soon or late. But it is time to invest in some projects that is why buying any currency at a low price is the best way to make money in the future if we can wait for the right time.
