Re: Isn’t this just the modern (modern?) equivalent...
I bought a miner with a voucher I got when I left a job way back. I pool-mined a proportion of a Bitcoin and watch the value go up, when there was enough to buy a rather nice bass guitar I took the money to cash but left a small amount to cover fees and round down.
Now that bit I left behind is enough to buy another bass. I don’t know whether to pull it out or leave it to grow more. When I look at the activity history, the current value of the amount I took out would buy a new Tesla.
