We can not do anything. Is that to keep their bitcoin and encourage others to do the same. But this will not help much.
It is not a secret for any of us that the crypto-currency market is subject to manipulation. False news, insider information - all this plays into the hands of large market players. When you have a lot of money, you can always pay a little bit, so that the news is useful to you in the media.
The price of bitcoin will always be tied to the average payback of mining. With the increase in costs for mining, the minimum price of bitcoin will also increase. After all, if it falls for a long time below the profitability of mining, people will simply disconnect their farms and the whole system will die. Thus, I believe that we should not try to increase the price of bitcoin, but use every drop in order to buy as much as possible.
