Anyone can buy sats which are smaller units of bitcoin and still get an impressive amount of return however basing on op’s title of this post “no risk no gain” I am guessing that they wanted to maximize the profits that they are going to get. You could have done DCA method like a lot of us who can not afford to buy 1 btc at its current price but honestly if I had the money to buy 1 full btc why wouldn’t I?
