You only need to do all that if you want to get them for "free" - if you consider all that time and effort of zero value!
Much easier to just buy them with your own money
The huge advantage of Bitcoins (and other crypto's) is that sending & receiving money to/from casinos (and anywhere else) is extremely quick and hassle-free.
Also the other party doesn't get to see ANY of your personal details - bank account numbers, card numbers, or anything - just your unique transaction reference number.
The only down side at this particular moment, are the HUGE swings in the $/Btc exchange rates which could mean you lose $ doing nothing.
Of course, you can also make $ doing nothing - which is why so many people started investing in cryptos recently!
