To get these returns, BTC would have to appreciate 100x in value and you would still need those 200k$. While it has done this before, past returns are no guarantee of future returns.
If you want to finance the 200k$ with debts... well... the percentage can kill you, or require you to or in a sizable chunk of income to pay it off. (Mortgages in some cheaper places in US are this size. )
