As far as I can see, there are a number of factors that suggest shark's involvement in this market. In recent days, market capitalization has fallen sharply.
Of course they are here only to make price down for their own benefit they are buying low price they use to sell their bitcoin if they hold and then they wait till the price gets low, so again buy a lot of more bitcoin so according to me they are really taking part in making the market manipulating so we should not help them to get benefit from our saving, just hold when you see price is getting down.
