last 15 years bitcoin ROI is 50%/year or 17% monthly (compounding) and the best strategy to grow own wealth is trading, algo-trading, futures, copy trading?
if btc returns 50%/year on avg and with trading/algo/trading you can easly 😃 make it twice then 1000$ in 15 years will become over 32 millions dollars (if the exchange dont goes bankrupt)
