I think bitcoin will start declining in a few years and fade away.
Something else will replace it that will cause people to shift to it.
Internet folks are very fickle. So I will take as much as I can take and give nothing back.
See them apples? you like them.
Once upon a time I worked for a startup that was purchased for 250M USD in cash. This was around 1999. We just had to park our *sses at the parent company for a year or two waiting for our options to mature and pay out of escrow.
One individual was sitting on 1M USD but he chose to LEAVE that money and become the first engineering hire in a new startup. The company was a *SURE* thing... until the market imploded. 5 years later I (and many of the same engineers) were working for another startup and it turned out the company he went to was trying to re-purpose their product to compete in our space. They failed, we were sold for 100+M.
You may think BTC will fade away, but I hope you have the foresight to save at least 10%-25% just for your own mental stability a few years from now...
