People need a real reason to use bitcoin over fiat, and so far I haven't seen really compelling reasons. That's heresy, I know, but to me bitcoin works much better as an investment tool and store of value than as a currency to be adopted for spending. But we'll see.
But without real utility, why is it a good investment and store of value? without a reason to use it, why does it have any value at all?
There's no need to let you see in order for you to believe it because adopting bitcoin nowadays is very rampant over internet transactions specially in tradings of cryptocurrencies. Its not impossible that adaption boom is coming because people slowly grow with their knowledge of using btc specially when they found source of earning it and they gain skills of altcoins trading. Gambling online was just a one way of adaption proof to let people knew that adoption boom litteraly now.
