Yep. I agree. Also the speed in bitcoin has been an issue for me, but I could plan around it. The miner fees though as the value increased were ridiculous. The worst I personally saw was somewhere wanting to charge me $100 to move my currency. At that time $30 was happening everywhere. So if you wanted to use it as a slow currency to purchase something for $5 you'd actually pay $35. If you wanted to but something for $100 you'd end up paying $130.
That is ONE very expensive fee. Couple that with the slowness and I just don't see it as being a long term viable investment. I do think it'll keep doing ups and downs, but I expect things to replace it.
I was mostly in ETH and I'm glad ad Eth declined less % wise than the other currencies I am in.
I have almost nothing in the currencies you said to avoid. What little BTC I have is on coinbase to fuel my SHIFT card. Yet, I don't actually plan to invest a lot there except for short periods if a nice up trend begins again.
Yeah I converted BTC on bittrex to BCH, ETH, and LTC and tested transferring all of them to coinbase. LTC was the fastest of the three. It also charged me a $0.30 fee at the time BITCOIN fee was $30 to transfer.
