I thought CFD's and short-selling, but when it go's up a lot, I don't have the equity to hold the positions and they will be terminated/margin call. Also I don't trust the brokers, will they pay when the fall is huge?
We can discuss about a crash yes or no, but for me this is not a question anymore. The only question is, how can I make sure not to regret this opportunity this time.
Forget about trading, you are going to get absolutely rekt in the bitcoin market. Just look at what happened renctly. A ton of people thought $7200 ish was the top, then we had a pretty big correction, it went up again and many traders started assuming it was a dead cat bounce and $7200 ish was the top. This is where a lot of people started shorting expecting a couple weeks of correction.
Fastfoward 24hours later and we hit a new all time high of $7500... moral of the story is, you can't predict what's going to happen.
I would not do any margin trading, but the only margin trading I would do is going long on bitcoin x2. As long as bitcoin doesn't go below 40% you should be ok.
