If I dont claim how should I buy the tickets. And it says its most efficient with buying the tickets, so I tried that. Never touched the game since I would just loose stuff, with the tickets I at least get those. It doesn't say I have to do both.

Do I have to get the other half from the "multiply game", the site just says lottery tickets are 20x faster for gaining the bonus so I went for the most efficient way.

How is it done? Should I just leave it an claim a certain amount until its enough to "buy" the bonus? How much do I need? And if I loose the bonus over time then there is probably no reason to build it up in the first place.

Also what do they mean by "Play jackpots in MULTIPLY BTC to increase your bonus 4x faster and buy lottery tickets to increase it 20x faster!"

Increace faster than what, it doesn't increase on its own, its decreasing, this makes no sense.
