I'd recommend the best way to grow your bitcoin is to:

- Not visit dice sites.

- Avoid anything that sounds too good to be true.

- Sell BTC on Local Bitcoins.

- Use services like Purse (No joke, it takes some time usually, but I order big orders on Amazon; like $500, then put a 35% discount on it for Purse... usually within a month it gets bought). Then use the cash you saved to buy more BTC.
