Thanks, can you train someone on cryptocurrency trading or give a good reference?

What do you mean by all of that ? Somebody tried that service ? I smell something fishy by that, what do you mean we can trade bitcoins ? I think your main goal is to promote your own refferal link here which is fine, but still let's wait for some real reviews from somebody;)

Wazua is about sharing knowledge. If I get a win-win situation for you and me, why not? The reward from that referral is peanuts anyway, but you pay 10% less fees for 6 months compared to direct registration. But that's besides the point. I just wanted to let wazuans know how to short/long crypto using leverage. If any of you guys have doubts about using bitmex, do your own research. I have personally used it many times but it is always good to do your own research too. Good luck.

Crypto trading is a high-risk business and traders hsould be very careful before deciding to invest hard-earned money in such. You can get a lot of profit by buying low and selling high, but the chances of losing are higher, and scammers are all over to pounce on unsuspecting investors. Be sure before taking up a project

The scheme of bitcoin shorting looks as follows:
If you feel that bitcoin is going to decrease at a faster rate than the amount of interest typically charged on a bitcoin loan you could borrow bitcoins (from this forum or elsewhere) and offer USDT as collateral, when you receive the bitcoins you could potentially sell them to buy USDT, after a month you can use that USDT to rebuy the bitcoin and give it back to the lender. If bitcoin decreases more than the interest amount you profit. USDT should be considered a very stable collateral so you may be able to get a lower interest amount. If you are expecting a dramatic downward shift in price your profits would likely easily offset the interest cost.
