If you don't want to participate in volatile speculation, that's fine, the average person shouldn't. But there is no other way around it.
You're referring to a pump and dump scheme as "phases". You don't set high values by scamming unsuspecting fools.
Any and all securities go up and down, whether it is justified or not.
It's not exactly a ponzi or pyramid scheme, but the manipulative intent is clear so a new term is needed.
It's a Satoshi scheme.
...hence the "pump" stage of the pump-and-dump scheme being conducted quite extensively, with all forms of scammers publicizing the immense virtues and magically perpetual low value of bitcoin, hoping that the next batch of fools and idiots open their wallets to finance the value pumping.
This happens every day in securities. Those "pumpers" are called "analysts". They sometimes work for investment banks and research firms. You can choose to follow their advice or you can bet against it.
Apple shares were $0.50 (unadjusted) in its early history. By your definition, anyone espousing the future of Apple and computers at that point is a pump and dump scammer.
Apple and stocks also generate value, whereas Bitcoin and PoW software burns electricity/value.
This is specific to crypto currency supply production algorithms.
Coin supplies are created by running the software. Bitcoin and many other cryptocoins use a rule that lets the first users take control of the supply very easily by generating the coins for very low CPU/GPU difficulty. After a few weeks, the work required to produce more coins doubles. This just lets a few users control the supply, wait, and attempt to convince new users the coins are rare because the production/mining has become significantly more expensive.
tl;dr: early miners generate most of the coins inexpensively, and try to sell to greater fools because the software stops creating coins as easily as the first few days
It becomes a ponzi scheme when the only value from early shares comes from investment in later shares. That's what's happening with bitcoin.
Satoshi made a machine that prints money if you do work. He made it so it only required a small amount of work to begin with and as time goes on, someone else with the same machine and the same work gets less. It's made even worse because there were less users battling over the larger easy production near the start, and more and more users fighting over less and less output.
tl;dr it's even more malicious than a ponzi
