Statistically it is very exciting bitcoin, when prices really fall. People can be hit by it, but the process from year to year is very real bitcoin growth. So, when low prices like now are suitable to put money to invest.

It is estimated that there are over 2000 Cryptocurrencies and more are being shuned out steadily.
And the few exchanges available are exercising monopolistic powers in the sense that they charge huge listing fees, transaction fees etc.
I think the creation of new Cryptocurrency exchanges is in order as there is need to break the monopolistic powers of these few exchanges which will make  the market competitive

Everyday, we are seeing new crypto currency exchanges start working. So many platform has already opened. But Is that OK? I think volumes are seperating. How this effect prices?

They are called manipulators. They manipulate so that they can make a profit. We are all very difficult to avoid because they have very good financial abilities. All we can do is wait, we have to be patient and take advantage of every momentum that is in gaining profit.

I think the indicator that caused the decline was not only FUD, but with several episodes that caused the fall of bitcoin by the actor. and we can see from the case that happened to the bch hardfock. and the accident happened bitcoin experienced a very big correction, currently the value is $ 3K. well here is fud working accompanied by a big actor

Certainly there will be times when bitcoin will go up again in value. Maybe it will be several years from now. And there is no point of panicking. Hold as long as you want and as long as you don't need the money yet. But if you really need your money then never wait for it drop too low and be back up maybe 5 years from now. It's a long wait if you really need your money, even a year is very long for someone who wants it for immediate need. So if you really need your money never store it in bitcoin otherwise you can do so even if it takes a hundred years and let your heirs claim it for you.
