I´ve $50k coming on stamp @tuesday/wednesday. To be honest, I´m not sure if BTC is at its end or will it rocket up any time in the future? Should I risk the $50k on this BTC game and maybe double it one time or should I buy a nice car and waste my FIAT in another way?

I dont need that cash in near future so it can be a long time investement but after all this shakings I´m not sure about the BTC future. It seems like the BTC price is too easy to manipulate. If big banks or governments gets into BTC they can shake all the money out of poor peoples pockets with their huge BTC amounts. If they not did this already the past 2 days.
