There is speculative trading in stocks and bonds, but not as frequently. It is a choice that a trader can make, though and hasn't been regulated away. I have no problem with government regulation on Cryptocurrency for speculation if the same laws effect the trading of stacks and bonds.

The "green" issue of Crypto mining is a harder regulatory issue for our government to get involved in, though. While on the one hand, I applaud their pro action, on the other hand, the hypocrisy is on a scale almost never seen. A government which has simultaneously rolled back environmental regulation, wildlife areas and expanded oil pipelines, shale extractions, fracking and offshore drilling while continuing a war on "terrorism", which is an ideal, not an enemy. A forever war, if you will. This is a polluter much bigger than crypto miners, so you'll excuse me if I have to take the concern about the environmental impact concern from the Senate all that seriously...... sorry. Went off the track. Either way, there are larger polluters to tackle than Crypto that take less control away from people.
