Your post seems too focused on price. For instance your point 2) Decentralization. Here I was hoping for a technical reason that you have FUD due to lack of decentralization in the way blockchains work, which I might have related to. Instead this is only focused on price. Your point 3 doesn't look at the tech either, but yet another price/adoption curve which may as well be tulips. Your point 4 now relates to the actual tech, and that's good. This is what you should focus on more.
At the end of the day no boom in history was without its detractors. If everyone believed each revolutionary thing would be the future, it would already have a lot of serious investors. Crypto is not yet a serious market since its market cap has never reached even 1 trillion USD. Whilst people now are skeptical of it, crypto has immense and world-changing potential which you do seem to realize. It might not be now, but sometime in our future as a society we will look back with awkwardness at past societies, like ours currently, whereby power and wealth was generated via centralized families, cartels and corruptible enterprises such as governments and corporations. These will all still exist, but the really important things such as voting and money will be decentralized. How could it not be? Once you understand the idea, you cannot ever think of it as shit again. Since the idea is revolutionary and so very, very obvious how necessary it is given human nature. Once each and every person in the world finally "gets it" with decentralization, that is the time crypto will take off.
If you're looking to make a profit, who knows, you might not make it in this lifetime. People really are incredibly stupid when it comes to common sense, and it might take later generations to grow up with these systems in order for mainstream adoption to occur, I cannot say. Make no mistake though, the concept of decentralization will revolutionize our world. Whether this occurs in a blockchain, tangle, cyclic graphic or a pair of underpants, no one can say. But the entire concept of purely trustless systems will be game changing for our world and species. And Bitcoin will always be there as the gold standard. This I fully believe. I just don't know when peoples awakening will occur. And no, s-curves and other charts cannot predict dumb mass-psychology. You over-estimate common sense too much when you let a variable represent it.
Until crypto becomes mainstream, for now my debts are in fiat currency. So yes, until that day, price matters. If I were not in a loss position, I would be comfortable with the wild price swings, because I know that worse comes to worse I can sell everything and not be in a worse position than what I started. But that is not the case. In a loss position, it is very stressful to see btc drop $2000 from where it was a few days ago, and TAs predict it may go down to $8200 or lower. It's stressful when I thought we had exited the descending channel that we were in for 2.5 months. Now we've re-entered the descending channel and so those dire predictions of $5200, $4900 and $3500 are now back in play.
