My plan is getting rich by hold the bitcoin and trading, these are of course the most common methods but I like this methods because there are also the easiest and fastest ways if you ask me.
Another fact is that the bitcoin itself has a bright future so holding is good right now, with the halving and signs that the price is gonna rise there is no doubt its gonna rise.
The last method I use sometimes is exchanging altcoins to bitcoins, its sometimes pretty profitable if you do it on the right moment
