That's good to see bitcoin helped people increase their knowledge even in other fields. However, for example, this one is very much general not it's not just about bitcoin or any other asset. You may already hear people saying don't put all the eggs in one basket so if you made a mistake and lose some part of your money you will still have other parts of the assets in other safe places, it's nice to see you learned that from holding bitcoin but you could even learn it before entering this market.
That's right, if you do something like lets say an ordinary investment on stocks, this has been done for many years so far and that's why it is not really a shocking result.

Which means you should be able to put them into different brokers just in case.
