Of course, the first impressions of your resource are very positive, but it seems to me that a hundred satoshi as a bonus does not affect users very much. In addition, you need to consider that poker players are a narrow circle of people, and therefore you need to introduce other types of games, which of course should attract more customers.
Actually those 100 satoshi's are affecting the game a lot.. in a negative way.
For the lowest 1/2 tables - I just test it and with a simple match figured it out that there isn't any means to play regularly but all-in every. And get another 100 satoshi's if I lose. This is corrupting the whole game and conception.
And everybody else is doing the same.
The option to play at 1/2 doesn't exist anywhere else on the internet so giving people that option is perfectly reasonable even if play is not at the same level as you'd expect at a higher level. It gives people who wouldn't otherwise play an opportunity to build their own bankrolls and play at proper stakes at a later time.
You'll find the play improves a lot even just going to 2/5 which is well within the reach of most players if they're willing to spend a few minutes to build up to the 500 chip minimum.
But giving people the option actually does bring in new people who wouldn't normally play, regardless of what other incentives they're provided with.
