You recommended good coins BTC and some altcoins which are the top cryptocurrencies in the market. But if OP want to achieve his/him goal 25k$ to 200k$ of course he/she need to take big risk with another risky coins which are big pumping and dumping. And if he/she want to lees risky investment when so difficult to achieve this goal.
Actually, this goal is not difficult for OP to achieve as long as OP has the patience to do it regularly, because now Bitcoin is at an all-time high which is a big win for people who have bought at low prices before. So every extraordinary achievement is actually not difficult as long as we are able to wait for it after daring to take risks by buying it in the past, and for now it is actually still quite good if you still want to buy Bitcoin with some of the top altcoins on the market because their price movement potential is still hasn't disappeared in a while.
