The middle of May 2019 was just a period of a good increase in the price of bitcoin, which began on April 1 and continued through the end of June. During this time, the price of bitcoin soared from more than $ 3,000 to more than $ 13,000, an increase of about four times. After that, with a general slow decline, there were only short-term price spikes in bitcoin. But altcoins this year have not pleased us. During the price growth of bitcoin, they generally remained without any movements. I would like to finally see an increase in the price of altcoins.
