RE: @movingman gets Naked in the Name of Transparency - Open Portfolio- Up to Date..
It is true that alt coins offer so far the biggest opportunities for big and fast profits. Bitcoin nevertheless has over half part over the cryptomarket, it is dominant and will remain most likely dominant. The is something called ''historic snapshots'' at coinmarketcap.com. Take a look there, you 'll see how tokens rise and fall over time.
That being said i think privacy coins will be something that will endure the ebbs and flows of the market. There will always be (and actually grow even more) a deep web market for illegal or restricted goods and privacy coins will be the medium of exchange. Right now Monero reigns supreme in that area but future projects could become supplementary or even replace it.
When it comes to wallets take a look at Coinomi. It is open source, supports a multitude of coins/tokens and has private key extraction. Perfect for using and old/cheap smartphone as a ''storage unit.''
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
