Politician are investing in cryptocurrency but some of them don't want to fully and openly acknowledge because it might influence a lot of people and the local bank might also be affected.
To OP, what I really missed about cryptocurrency is the unpredictable price of all cryptocurrency and it unstable price. If this issue can be fixed then probably we investors can know when to invest and when not to. But alas, I guess this can never happen.
I personally lack the stability of the crypto-currency market. But I think like the other shortcomings over time it will go away.
There are projects out there that are solving unstable prices. I personally like Xaurum coin, because it is gold-backed and in the same time the ratio between gold and token rise and when it does, it can never decrease. So I can not loose my investment and in the same time I can only profit. I hold this token for long-term.
