in my opinion, to be rich with bitcoin, is to make a trade. because bitcoin market and altcoin. Because the coin besides bitcoin is also of no value, and the difference between the price of the coin we can profit.
Trading bitcoin and other coins could be a good idea. But you have to trade good coins, not the scam coins.
Most altcoins are scam coins but it doesn't mean it's impossible to make some profit trading with them. Whem a new coin released it generally gets pumping and it goes from say 60 sats per coin to 250 sats per coin. If you manage to buy at 60 and sell at 250 couple of hours later you can profit from this but from my experience it's very hard to do. Also you might lose when trading with "good coins" actually.
