You can try short trade or fast trade you can do this on active altcoin you can buy it and sell on small amount of profit that's small but fast i started with that with a started trading with just 50k sats or 0.0005 btc and now i have 0.2 on my trading wallet and until now that's my strategy to earn but if you wat bigger you can try long trade it consume long time to trade but big profit that's my strategy just pick what you want
