I personally had a worst streak on dogecoins dice testing only, I had 54 in a row...
I sent those coins directly from freedoge.co.in but lost them due to that streak, the coins were just 150 in total, and I was testing the dice with 0.00001 Doge per bet with x2 on loss...

54 at 49.5% is quite a lot. you probably hold a world record or something special for that streak.
whoever has large bankroll takes the other one into it 
how much big bankroll needed to play at dice but we have to keep in mind that thing losing streak with 2x payout can go up to 30 in a row if got that kind of losing streak with martingale than we can overcome or not? using martingale is always risky where house edge exist.
its simple as that ... explained below
you have 10 BTC and site has 1 btc then start with 0.05 btc bet and most probably u will eat the site's BANKROLL
If the site has 1btc bankroll, they they probably only allow max profits of 0.01 per bet (1%) Thats at a maximum. At just-dice, you would only be allowed 0.005 max profit (0.5%). Also, the max bet would also depend on the bankroll size, as the % stays the same. This would make it more difficult that you will eat away at the sites bankroll too much, even by playing martingale. But it is still possible to eat a lot of it. (maybe 25-50%?)
