Some of these seem quite feasible, but considering how volatile the market is, I would refrain from making any claims towards the price of any of these, especially not in such a long run. I don't think that we need more speculation. Actually, I think that speculation in crypto is becoming quite dangerous. Most of these have a potential to burst and if they burst, many of the newbie "investors" could lose faith in the blockchain (or the Tangle/DAG) technology as well. This is not what we want. We need more real investment, not speculation by hyped-up newbies from the mainstream. And any claim promising such high ROIs will almost certainly stimulate the latter.
