Well, its everyones strategy. Buy Low and Sell High. And besides, it is the main principle of trading isn't it ? But of course, to become a successful trader. You must be familiarized with the fundamentals.
Great for you, Honestly we are partially alike. But for mine I got my starting capital from gambling and not from signature campaign. I use the ARBITRAGE METHOD which is a Short-Trade. Now let me explain what this method is; in this method, you need 2 trading sites (example yobit and c-cex). Why you need 2? its simple. The price of the exchange between different sites are not the same. Example: Yobit: BUY-45 sats SELL-44 sats , C-Cex: BUY- 57 SELL- 55 . What you will do is that. you will buy in the site where the coin is much cheaper. Then you will transfer to a wallet of the other site where the price is high then sell it. Easy right.
55-45= 10 sats profit. Not to much isnt it. Take note: it is only for 1 quantity. If you buy at least 50K or something:
50,000x10= 500,000 profit. Now, decide yourself if you are going to use this.
