Right now, the coin mining is closer to squatters heading west during free land grabs. Once all the land is claimed, that's it.
That's true, but not really relevant. The coins have value because other people want them. Same with paper money. Every time I hear about someone saying paper money is worthless because it's not backed by gold, I always offer to haul that worthless shit off for them.... so far nobody has taken me up on my offer. As a side note gold isn't backed by anything, yet it's worth a lot...
I will give out one 'secret' that I think I'm going to try... In 3 years I'm probably going to buy a bunch of gold before the election. My theory is that if a democrat gets back in the white house, gold will take off because the economy will tank. If Trump gets reelected, gold will stay put. So I'll either win, or won't lose. I'm cool with either of those outcomes.
