At some point of time in the near future I reckon the crypto environment will be regulated.
I can imagine that governments do not like 'stealth coins' like monero and will try to forbid these. One such example is the Japanese government trying to push exchanges to drop altcoins favoured by criminals (Monero any1?

). I foresee more of these kind of actions from governments.
Personally, for this reason I will not invest in stealth coins like Monero.
