Buy a ledger nano s. great usb wallet to store all coins.
I jumped on POWR at 10cents. power ledger is just starting and I see it jumping min 50 dollars in the next 5 years. great company with great future. rumor has it Elon musk is interested in this company. to be honest I would get on the train now. as I am sure it could crack $2 BY END OF YEAR.
If you have a small bag on coins then coinspot is fine to store them on. just make sure you have 2 factor authentication.
