Of course, remember not keeping your eggs in one basket? If you remember, it is quite possible for some people to diversify their bitcoin storage in several different wallets.
I believe there are many new millionaires in this industry regardless of the role of the institutions that own lots of bitcoins. Many people have chosen bitcoin as a long term investment asset, store of value and such. But data may not matter because it will only change over time, but of course it makes people more optimistic about bitcoin.
Obviously there are many reasons why storing eggs in multiple baskets is far better than storing eggs in one basket. This is just a mathematical number of course one can believe it or not.
There are many new millionaires born in this industry and also many reasons why bitcoin is the most rational choice to choose. A lot of people have understood the advantages of bitcoin and it's exactly what you said, so it doesn't matter to me how many new millionaires are born in this industry. Historically what the OP said is also most likely a longtime investor affiliated with many new wallets.
Of course, but still address data strongly supports the asumtion that many people choose bitcoin as an investment regardless of whether they are new investors, existing investors, institution wallets, exchange or so on.
No one can guarantee whether they are new investors or old investors? and for me it doesn't really matter because awareness of bitcoin adoption has grown far from before, this is good for all of us in utilizing bitcoin as an investment.
