Ethereum : Seem like a good product however it is a knock off centralized fully manipulated version of ethereum classic. Then why does it worth more ? that is simple "propaganda", "poor research" and "blind sheep-like followers"
Dash, Litecoin, Bytecoin, Dogecoin etc. : All copies of Bitcoin with different maximum supply. Has owners that simple want to cash out in USDT (USD Tether) or Bitcoin.
Things of value either gains value because of it's USE or simply because there is an Illusion of value created for that thing.
Ripple : This will F you in the Arse. You came running to cryptocurrencies probably because you are broke and want to get rich. Rich people might come because they want to get richer. Smart people who eventually will become rich came here to escape the clutches of the banking system " the same banking system that ripple was made for" they are going to continue deflating that until the end of time. Read all about them and don't go adding yourselves to the sucker list.
Monero, Bitcoin, Ethereum classic, USDT : These are coins with specific USES.
My Thought ; Thank you for all your support during my steemit venture I hope my work "that aren't life stories" was of some help to some of you guys and I will continue.
