Why didn't this exist 20 years ago.

Oh, man... don't I know it.
In the early 90's to just past Y2K I ran a software development business (Windows utility tool) and while I did everything *but* the actual coding (contracted that out to overseas cheaper devs) it was still a high-energy pursuit -- up all day doing tech support and shipping disks etc then up all night doing testing, bug reports for the devs, UI design, help file code, website, etc etc etc
Cokes & Snickers to keep going, grab an hour or two of sleep under the desk from maybe 6am to 9am, then back at it day after day month after month... yikes, that's totally a young man's game and I could never handle it again nowadays... LOL
Wish I could though... contributing more to the crypto economy now would be great if only I had the energy.
Best I can do now I guess is just BUY and HODL as much as I can afford
I hear ya! I designed and oversaw the Y2k response for Cherry Semiconductor (acquired by ON during that period) and it was amusing that everyone said "Damn what was all the fuss about we didn't have any problems" completely missing the point that there were no issues do to our hard work.
So what's the deal on the bitcoin forkokalypse and coinbase adoption??? It's messing with my plans for the next six months, LOL.
I.e.:Huge price pump (BTC'ers move their money to XMR), take money off the table, price subsides, buy back in bigger, wait for the September hard fork, profit big time (and keep hodling a chunk...

)
I have no clue atm. Have not had the time to watch the market.
