I had coinomi a while back, and bitpie was also good, I guess they all hold more coins now, when I had them before they were all limited lol. I am to research on Security Tokens, something I want to check out what ones are security tokens as they will have a great roll to play in the beginning stage of this.
I will get one BTC to put on a separate second nano s for safe keeping a decade or 2, theres no question of a doubt that BTC is the king and mostlikely will always like you say have most of the crypto market dominance
