Taking a long position with bitcoin is not such a good idea anymore. All indicators show that the chances of it doubling in price are very slim. You can make much more by arbitraging coins..
This is true, but if you really do not understand how to do it, how the fuck are you going to do it? Most exchanges are asking for KYC right now and maybe they freeze your funds because of that.. it is something very hard to do.
There isn't much to understand.... You buy exchange a, and sell on exchange b..

Whats wrong with KYC? unless you got something to hide...I personally had my identity verified on every single exchange that I use for trading, never had any issues..
