I think all richest people in the world always search ways to make money. BTC are very useful to make money but they aren' t for lazy people. Btc are for people who love to start something from zero, and i am one of them.
Yes bitcoin is only one currency that it can make you richer from zero. Because there is more example on bitcoin forum that how poor become a rich from bitcoins who every started from 0. If it is about lazy people that lazy people also can work in a bitcoin instead doing jobs in the economy. So now a days everyone want to work in bitcoin.
