In Georgia, I’ve used three different currencies.
The Soviet ruble was the money of my childhood. We called it maneti. I was nine when that system disappeared.
After the Soviet Union collapsed, we introduced the Georgian coupon in 1993. It was meant to be temporary. It had no coins. Only paper notes. Inflation ran so fast that prices changed constantly. At one point, one US dollar was worth more than a million coupons.
In 1995, the lari replaced it at a rate of 1 lari for 1,000,000 coupons.
Three monetary systems.
When you’ve seen money change names and lose value like that, you stop assuming it’s permanent.
That experience is probably why I take Bitcoin seriously.
