If you hang around the tech scene for long enough you will see some absolutely amazing ideas being turned into businesses. Some arrive too early to be successful, some aren’t executed successfully and some are just so ‘out there’ that the public at large can’t get their head around the idea, no matter how good it is. Bitcoin (and cryptocurrencies generally) is in that last category right now. The potential for this area is huge. But currently, even many sophisticated early tech adopters are scratching their heads unless they have a really compelling personal reason to start adopting Bitcoin (like buying large quantities of drugs on the dark web or moving vast sums offshore from China…).
