if in my opinion. better now choose to invest short term. and invest using paper currency. because the price of bitcoin and altcoin is now increasingly destroyed.

it seems the safest place to store bitcoin that you have and for beginners is the blockchain, yes you can save the bitcoin you have on the blockchain and there the security is very high because it is stored directly in the blokcchain data which is the technology of bitcoin.

I think school and college textbooks can be kept in the middle of our time in bitcoin.It also tax and revenue are live in bitcoin by good position.
