I am asking me this Q:

If everyone is holding.... and the last block is mined, supposing that on the planet earth there are more than 21mil millionaires, and each of them as a status of symbol would like to have at least 1
BTCThere will be no chance to serve them all
When the last block is mined and still people continuing to keep hold without making it get used the demand will increase. What we hold will surely get into the market at some point, if there isn't any possible whales will manipulate. This manipulation will create panic and make small volume holders to release to the market.
