The people of the crypto world, especially the people who have invested a lot of money in the crypto world and those who win many bitcoins are always spreading their optimism. But that optimism serves to convince more investors to enter the crypto market so that the price will increase a lot and the guys who have invested a lot of money in that market and the people who earn a lot of bitcoin will get a lot of profits. This is looking like the HYIP/PONZI sites where people are trying to convince more investors to invest in the ponzi site so the early investors get paid.
Bitcoin, do not need that kind of advertising, people should see the great advantages that bitcoin has and if these people like these advantages, then these people will buy bitcoin.
