They know the worth of the coins, for which they additionally bought this large amount of bitcoins at 28K USD. On the other hand, there are some people who keep complaining about the price and always cry because they missed the lowest possible price to buy. They are forgetting the fact that bitcoins are limited in number and hence very valuable. So if they are able to buy the coins at 30k USD, then they will also be profitable if they hold them dedicatedly for an year. Moreover, this huge purchase will definitely shake the crypto market. Let’s hope Bitcoin touches 35k USD soon in the first half of April.
