I've been extremely interested in Mimblewimble since it was first presented a couple of years ago, though I only recently heard that grin is finally launching its mainnet soon.
Me too, I have been waiting for this for a very long time.
I have talked about it with a few very crypto code-smart people quite a while ago and they also seem to have high hopes for it.
Note that due to the way grin emits its coins, prices are likely to start out high and steadily drop for the first few weeks/months.
Good tips. Thanks.
I hope to get in on this too, hopefully somewhere near the right time, and let it ride.
