hm, so are you saying that in 2016 there were 11,5 million active wallets? It should be way higher today if that is the case.
However, we still have to consider people with multiple wallets. I myself have 4 different active bitcoin wallets for instance.
I think that a lot of crypto enthusiasts have more than one wallet. Especially crypto whales)
yes, for sure, the accurate number of individuals owning bitcoin is probably less than half of all active wallets.
