I know, everyone has different characteristics in making money, and for me staking on an exchanger is not very profitable, especially using USDT. It locks up our money for a long time and to be honest, it is very boring because when the cryptocurrency market is bullish, we cannot enjoy the fun like other people.
What is suitable for my investment style is holding for the long term. We can see that BTC is the strongest coin currently and is a barometer for other cryptocurrencies. I can suggest you to hold BTC in a personal wallet. You won't get a certain amount of BTC for the holding, but if your goal is money, at least the exchange rate against FIAT will rise in the future.
