Agreed on coins... but: crypto tokens will retain value, *IF* backed by precious metals. BTC and dogecoin going to zero fer sure.
I don't own any, and wouldn't buy any - for the simple reason that the perfect wealth-retaining "money" is available for purchase right now: Physical Silver (not paper, silver in physical possession ONLY). However, seeing lots of discussion of the various cryptos. I also understand that purchasing crypto's like dogecoin, token too, looks very complicated, dealing with various "wallets" and needing to perform various conversions, depending on rules and compatibility.
With the transition to QFS/NESARA/GESARA, fiat disappears, and metal-backed new currency takes over. This kills the FED and fractional-reserve central bankstering.
Crypto post-transiton will be a thing, for sure, but must be as compliant with regulation (ie, metal-backed) as the currency.
Buy Silver! Go look at usdebtclock.com, and the dollar to silver ratio - it is now around $4800/oz. Then, go to a silver dealer - it is now around $28/oz.
