I don't know who mentioned arbitrage trading, but I'm not doing it for sure

just be careful when you do arbitrage trading because you need to estimate how long the coin will arrive in your wallet so you can sell to make the profit. I see you have good progress in your day trading and I think that you can make a big profit in the future. with doing this, you can increase your bitcoin and yes, trading altcoin can help us to make our bitcoin is growing.
