As someone who fell for a previous "BTC for levels" GoldenTowns offer, you should note that this guy is pledging $5 equiv. for reaching level 5. I've been playing for about a week, checking in three or four times a day - there's a lot of waiting for shit - and I've only just broken level 3. "Working" for this guy is like working for a wage of a dollar an hour.
Just re-read the OP and realised I was mistaken here; you're being paid the equivalent of 50 cents for a few hours' work. Unless you expect your 0.0005 BTC to rise in value by several thousand percent, I really can't see why you'd bother playing this game to earn BTC from this guy.
If you enjoy the game, go ahead!
Yo, bro! What crawled up your butt and died?? If you think what I am offering is too little, then you are more than welcome to create your own promotion scheme and give away thousands of bitcoin for all I care. Yes, what I offer for reaching level three is minuscule in the grand scheme of things, and there is a specific purpose for that. I will not begin to see any return on the investment I make for quite some time, and the payment structure is tiered so that it incentivizes reaching the highest level you possibly can. No, I'm not gonna pay you a big gigantic sum for reaching level three as that would ultimately incentivize playing up unto that point and then quitting because that sort of reward structure would create diminishing returns for the individual playing.
The way I've set things up rewards the user more for going further in the game. No, I'm not going to offer you a salary for investing a few minutes of your time each day, and the ultimate goal here is to put yourself in a position which will allow for you to profit from the game itself and not just the rewards that I will dole out.
Take your shitty attitude somewhere else, you're totally crushing the chill vibes and waves we've got going here. Don't crush my chill, man.
