I don't think N8snathan is the house himself betting on his own site, I do know that N8snathan does play on other site too beside bitvest.io, he seems to like playing plinko on bitvest with his customize line, that line won him a few big wins in the past, investor just have to stay on with their investment because the house edge will surely catch up with N8snathan over the time.

It is just a matter of time before the player lucks run out
