Regardless how much your bitcoin is worth today, make sure you don't lose them because we don't know how high bitcoin can go in the future. Your 0.01 BTC holdings might just be worth like $350 today, but who knows, while there are definitely no guarantees, it could buy you your future house sooner or later.
It is very true. As there is no other way than keeping the private information of our wallet in a place, we should be very careful about it. I know that it is really frustrating not being able to change the wallet access info (private key etc.) when we lose it somehow. But as I said, we have no other choice unfortunately.
