I think that it was really strange that in January when BTC went down all big cryptocurrency exchanges closed registration for new members and they opened it only when the price was low. Then at spring when the downtrend was broken(7000$) there were many news that cryptocurrency now will go up! But whales just made big shorts at 10 000 $and all the news said that cryptocurrency won't go up for along time and market went down to current position.
There is manipulation in the market that is correct but even if the manipulation in the market is as big as many people think there is nothing we can do, you need to find a way to deal with it, this is why many recommend holding your coins, if you have been holding for a year you have profits and anyone holding for a period longer than that have profits as well, only those that have been holding for 8 to 9 months are at a loss but if they keep holding they will turn a profit in the next years.
