We must agree that bitcoin and other crypto currency could not grow in price continuously and without significant fluctuations. Their price has fallen sharply, but we know the reason and this reason should be eliminated in the coming months. Therefore, nothing unusual happened. Now it is necessary to prepare for further raising of the crypto currency and therefore buy it at a low price.
This time is the best time to buy, It will be the last dump t these year,and we might see it pump by December. The dump and pump is normal on bitcoin so we should just repax and never do decisions right away without thinking.
