Thoughts on the following in 21018?
Ripple (xrp)
IOTA
Stellar
SIA
any of them going to rocket or crash?
We do not know the future and we cannot predict any news that can make any of them rocket or crash, but from the look of last year to this year and judging it with next year, I do not expect any of the coins you have listed there to remain the same. If it does, then it needs to bounce from the market. However, i still feel XRP is a time bomb but who knows? We can only speculate.
I love the IOTA project, and hope they will achieve some great things in the coming years

I really hope IOTA will make some pretty good move in the coming years cause I am not really that impressed at the moment as much as I love the project. But like they always say, patience. However, SIA is one coin I am even more angry at the devs. The recent dump was bad and it does not speak well for the coin at all, and I really hope they can recover. I guess we will just have to stay tuned and keep watching.
