I almost always use the ethereal purse MyEtherWallet. I consider it the most successful and convenient to use. I always choose ICO campaigns where ERC-20 markers are used. I tried using wallets of other platforms, except ethereum, in particular, Waves, I did not like them. After that I use only MyEtherWallet wallets.
Nowadays most of the tokens were created based on ethereum so MEW is bet ever wallet for a bounty hunter and some newbie were given some other thrird part wallet like downloaded from android app store which doesn't support any of the upcoming tokens which results in temporary losing of the tokens.
And most of the people don't here for just bounty hunting so they don't know about which wallet will be suitable een myself were given wrong wallet when I participated in a social media campaign results in loss of them.so being higher rank doesn't know everything about crypto currency.
