Here is today's interview with XAPO's CEO:
http://www.strictlyvc.com/2015/04/20/wences-casares-on-the-future-of-xapo-and-bitcoin/It was interesting that he quoted an estimated 12 million of peolpe using Bitcoin today.
As people pointed out on Reddit, it is overly optimistic number to say the least.
BlockChain.info had 70K wallets in April 2013, then it hit 1 Mil wallets in Jan 2014 (less than a year x 15 times growth). Now, another year+ has passed. How many wallets Blockchain now has? I would estimate at least 3+ millions, or more. B/c the growth slowed down in 2014 with the BTC price crashes etc. So just one provider has 3+ millions.
There is also CoinBase, Xapo, Circle, CoinKite, whole bunch of mobile Android wallets, iOS wallets, and everyoine else.
So maybe 12 millions is a stretch, maybe it is just a sum of estimated amounts of wallets from all major providers.
It would be nice to know the exact number of people who use Bitcoin, but at this point we could only "guestimate" it, still I think people need to pronounce those larger numbers in the press, business community, etc - to spread Bitcoin awareness and interest. In this case, it was published in StrictlyVC who serves business / entrepreneur / investor community.
So having a higher (althouth overly optimisctic) number like that quoted is a good publicity for Bitcoin, and it needs good publicity to somewhat recover after less than favorable 2014
If anyone has more accurate numbers in terms of how many people worldwide are engaged with Bitcoin, please share your numbers / guestimates!
Thanks!
