1 - Why are we not allowed to make more than BTC0.0374 per bet? (Max Gain: BTC0.0374)

Those limits are floating and strongly depends on current bankroll size, which is currently not very large.
Check our FAQ section for details.

2 - How much maximum can it go higher in number? (How many times exactly? Like 1000x, 10000x?)

Thanks to calculation algorithm nature, there is no any limits on maximum multiplier.
Few days ago, for example, you could see 69,677.19 as the result of 48077th round.
