The difference is that when you hold bitcoin today, you are sure that years to come, you will wake and still meet your bitcoin in whatever value it might be. But this cannot be said about casino tokens which may not be here by tomorrow. That is the great difference between holding BFG and holding bitcoin.
Correct, but Bitcoin doesn't pay you interest unless if you use a 3rd party and then you rely on that 3rd party, and still the interest won't be high - and here tokens like BFG pay you over 50% annually (as of now) which is quite massive.
Over time it's hard to tell, but if you pull out on time you can make nice gains.
With Bitcoin no one knows if 5-10 years from now it would be worth $20k or $100k, you can bet on it but there are no guarantees it would happen. Look at Litecoin, used to be $250 and more and now it's 5 times less than that.
