There is much consideration of why the cryptocurrencies are dropping its price. Some people are doing panic selling because they didn't know how the market really works, some are leaving in the world of crypto, because they lost huge a lot of money investing in it. But if the market becomes stable, how we buy or sell in order to earn huge profit. Volatility is need in order for us to earn money, we can't earn in a stable market.

There are many reasons for dump in prices as it is been witness currently! One major reason however is the unknown regulatory law, procedure or law as regard cryptocurency especially with regulators in the United State!

As I observed this year, gradually all the coins have declined, to the point where the coins are in a very low position of the highest price they have achieved. In my opinion, all that happens because of the cycle of the crypto that every four years experienced a jump. So on the way when crypto is not in the cycle of increase, the crypto value will only fluctuate in the decline that lasted for a long time.

People have been selling bitcoins and altcoins in panic because they don't want to lose their money in this market downtrend. Now is the time to buy some good altcoins and HODL. We need to be patient and use this opportunity of panic sales to buy more good stuff

Probably because bitcoin which is dependent all altcoins falling thanks to the massive sales!

Coins fall because bitcoin is very much fallen, but why he fell bitcoin is certainly a big mystery that is not an exact answer. Most likely it is manipulated

However I think that none of us know the real reason why all the coins are falling. And the reason is a lot of drop. The main one at the moment is because I think it is a fear that leads to panic investors and makes them withdraw money from crypto and I hope it will be stable again in the near future.

Its probably due to the market dip issues. This that is happening due to the volatile nature of cryptocurrecies. I believe its normal for something like this. The market is gonna  be nomal and stable again soon.

because bitcoin are drop.
bitcoin is pair for all altcoin,
if bitcoin drop, altcoin value will drop.
