No one considered that the most you can profit from a short position is 1x of the amount you used for short selling.
To illustrate, if the trader has $1,000 in his account and wanted to use 10x leverage - $10,000 - to short something priced at $100, then the highest amount the trader could take profit is $10,000 IF the coin crashed to zero. The only reason why there's a potential to profit 10x of the original capital is because of leverage, NOT because there's an exponential return.
The OP said that it might be easier to make 10x shorting. well, I think he really hasn't gotten into trading yet. Even when we get 2x profits when short, it is a very good thing. it's not as easy as the OP said. in fact, it takes persistence for it, it's not even easy to get 2x when going short. In addition, many people who target short, get stuck and end up holding on long term because the price of the coin they are buying has dropped drastically. Imagine making $10k, with $1k in a short amount of time. well, I think if it was that easy, nowadays people tend to prefer trading over investing.
It’s time stop thinking right and left when it comes trading or even investing your money because we need to think 360 degree. All the angle and all the bumpy rides along the way.
Chasing a dream of high profits in short period of time? Then just sleep on the couch and start dreaming about it because that is where one can achieve it. In real world things do not work like that but just the opposite. You need to have high level of plans with your investment and good skill set while trading the money.
It’s far better one think this through and do not day dream about such risky profits.
