I'll convice those by saying bitcoin is supported by mass adoption so yes, it's really difficult for bitcoins to survive without mass adoption. The more people hold bitcoins, the more secure the network is. Also the price will only rise if the demand rises which again needs mass adoption. So to see bitcoins succeed mass adoption is really important. I don't see any reason why common people won't treat bitcoin as an investment & monetary asset. Bitcoins possess all the qualities a good investment tool should have so it can definitely be reached to masses.

The word of bitcoin is already spreading like fire with bitcoins touching $100k. We already are eyeing mass adoption so much better can be expected in the future. I'm positive with bitcoins and so are hundreds of thousands of people with me.
