I got my first mBTC sometime in 2012, and ever since that date I have created dozens of Bitcoin wallets. I have/had accounts with dozens of cryptocurrency wallets and they alone should number ~20-25. On top of that, I had created a dozen or so wallets in Blockchain.info, before moving my coins elsewhere. It is hard to calculate, but my guess is that I may have created close to 100 Bitcoin wallets. As of now, I am storing my BTC in around a dozen different wallets (including exchange wallets, online wallets, hardware wallets and paper wallets).
Have you created such a large number of cryptocurrency wallets for security purposes or based on the technical requirements of your assets? Maybe I do not own a very large amount of bitcoin, but I have one hardware wallet, of which I am sure of security.
