Same here, but I did indeed buy coin. Mostly XLM, XRP, and ETH before buying a miner. Now I have some low price coin that I mined rather than buy. It's all a gamble like the stock market. Bought into some MJ companies TRTC and CVSI.... the two top revenue US traded companies (also a gamble since MJ still illegal federally)
Not for long; at least, not without some sort of fascist overthrow of state governments. Medical aside, there are currently too many recreational states for the fed to do anything about it. If they wanted to, they needed to do something before California stepped up. CA is too big to take down, population wise AND financially (recently became the world's fifth largest economy, I believe).
I bought some green stocks too, but the bigger issue is that it's early days for the industry. Phillip Morris and other biggies are starting to move into it, so it's going to get...interesting. All I wish is that I could invest in the company that makes the gummies I buy up here in PDX, because damn, they're too tasty. They should really include a bag of non-edibles with them, so you can eat a bunch after they kick in without going full on psycho...
And so as not to tangent too far off topic: I think that my Z9 may be my last ASIC for a while. Just for longevity's sake, I'm not a get rich quick guy, and these are great for summer, but by late fall I'll probably just want to upgrade to whatever the new GPUs are on the market to heat my house for winter, but I will say that I love the energy efficiency of the X3, B3, and Z9, I'd gotten very used to Antminers running up my power bill with their 800-1400W monsters.
EDIT--also I do buy low on occasion, mostly just through Coinbase when BTC drops below 6, LTC below 100, that sort of thing. Generally I just let the miners do their thing, though.
