Nice and useful.
I want to add for example under bitcoin wallets, you could write, for more wallets visit : https://bitcoin.org/en/choose-your-wallet (same goes for other coins if it is available in their official site only), it isn't hard to add tho and i recommend it.
For ethereum wallet you need to change bitcoin.org by ethereum.org
For bitcoin cash, i don't have a clue whether it has an official wallet : bitcoin ABC? please verify (or change the "official" title)
Don't know if i missed something but overall it is good work, please just make the required modifications then delete the image containing the error(s) then upload the correct one so i can give you +2 sMerit (or +4 sMerit if you add the link that i suggested for each coins ).
(Yeah, you can put it in imgur and share it in social media/reddit too since it is useful)

(will give comment for the other posts soon)
