#solana I have a mind and think a strategy that We buy a coin when its price is 140$ and then its go up and price 170$ then we sell it .convert in usdt.then we wait when again its price comes down on 130 or less then we buy it again.in this method we can make profit.
Anyone help me.I was purchase 1 solana when its price was 140$ and now its price is 175$ tell me how can withdraw or cell 35$ which i profit.and the actual 140$ will available back?
