For someone who knows nothing about bitcoin, it is not bad, for those of us who have known about it for a long time, it does not tell us anything new, they are generalities and there would be nuances to be made.

For example:


It depends very much on how you set it up.


These two statements are almost contradictory, as mobile payments are potentially insecure. On your PC, if you handle your bitcoin with Hardware Wallet it is very secure, but not mobile payments. It is generally recommended that if you want to carry bitcoin on your mobile it should be a small amount. For example, no more than 1,000 USD, but it also depends on your level of wealth and how much bitcoin you have.
