What are you talking about??? People who invest in bitcoin is not a stupid and I believe that investing our money in bitcoin is a good way to became successful in life and I know that investing in bitcoin is really worth it specially when we will keep our bitcoin for long term so the price of bitcoin have a chance to increase very high. The only person going to end up foolish is the one who doesn't invest in Bitcoin while he still has the chance those who saw it as foolishness to invest in facebook and other stuffs are regretting it today, hope you don't regret bitcoin investment in future.
