I guess if you do not have the funds to make this a profitable thing, maybe it wasn't meant to be for you? Have you considered that? The reason why they have many things from low amount of fun tokens to a very high amount of fun tokens is that they are offering stuff to people who do not have too much money like me and you, and also offer so much for people who hold a lot and can take advantage of the biggest prizes as well.

Just like I calculated recently here, it is clear that a very big whale could make more money here than anywhere else and that is what they are aiming at with the maximum offer, but the minimum offer is still viable for most people like us, and we could take advantage of that.

So, I do not know what I should be aiming at personally, but you could basically do the same, calculate which one would be the most profitable for you, and you could get something. Plus how many places offers free fun token? You could get free btc from faucet and buy fun tokens with it here as well, that's pretty awesome.
