How many people are actually using Bitcoin? ( Those who aren't merely using it as investment) ( those who are using it to make payments, purchase goods ,etc.)
I don't think anybody can say about it. Everyone can use more than 1 wallet for transactions and lot of people do this, using a specific wallet for a specific use. Not long ago a guy promoting the scam Onecoin was bragging Bitcoin has only 300k users. I was near to fail from my chair, i found it very funny
He is in fact more or less correct in his estimation
The basis for this figure is the number of transactions processed by the Bitcoin network daily. It oscillates between 200k and 300k transactions, and it is assumed the number of active Bitcoin users is somewhere between 300k and 500k. What is considered as an active Bitcoin user everyone decides for themselves, but this of course doesn't make the coin that the dude has been promoting less scammy (if it really is, in the first place)
I don't think that estimation is necessarily bad either. 300,000 to 500,000 people all coming together to use this alternative currency with the help or guidance of no government or single corporation. It's pretty amazing to me when you really think about it.
