In your study of Product life cycles, I hope they taught you that the average product life cycle is ~10 years.
BTC born in 2010, so 11 years old, past the age of collapse for most products.
New Phase is beginning of Government Banning of said bitcoin product,
if Bitcoiners don't find a way to stop the increasing bans due to their global energy waste,
then we will be in the decline cycle with a very fast ride on the way down.
If I were you, Check out Cardano and it is a New 3rd Generation Blockchain product
It solved the energy efficient issue
It solved the onchain transactions issue
It has capabilities Bitcoin can't even dream of.
It product cycle is just beginning.
FYI:
The thing Bitcoin needs to stay out of the decline stage is a design change to PoS,
but bitcoiners are refusing to evolve, so a permanent decline to $0 is possible.
Ethereum is evolving by switching to PoS design, so their product cycle will be continuing .
You are saying that bitcoin needs a redesign in order to remain relevant in the market. Also you noted that 10yrs is let's say average product life, now BTC is more than 10yrs.
But from mining table of bitcoin, it's estimated as the times goes the BTC becomes more valuable and scarce. It is somewhat confusing to determine actually how it will be in the future.
* The Product Cycle is more powerful, than the bitcoin mining table. *
* As Governments are going to have no choice but to ban it , to protect their power grids and their people.*
BTC has become more valuable as the number of altcoins have increased,
since this adds more bitcoin that have to offset the price of the market pairs with the altcoins.
Problems for Bitcoin , is more exchanges have begun direct US dollar pairing with alts,
which means BTC can now be left out of the trades all together.
Also the reason why Dodge is doing well, as it has many market pairing.
But as the Bans of BTC increase , more people are going to migrate to coins that
have cheaper transaction fees, are faster to transact with,
don't harm the environment or cause their personal electricity bills to increase.
Bitcoin is like Freon
(what they used to put in the Air conditions) ,
Once it was discovered Freon was bad for the environment, they started banning it use,
As of Jan 1st , 2020 Freon has been permanently banned in the US,
Expect the same to happen to bitcoin,
if they don't redesign their PoW to quit harming the environment thru unnecessary waste.
FYI:
While their are only 21 million bitcoins,
Look at what happens when it is divided
If the smallest unit of bitcoin was
.5 then their are 42 million units of usable bitcoins
.25 then their are 84 million units of usable bitcoins
Bitcoin allows eight places to the right of the decimal
.00000001 gives 2.1 Quadrillion units of usable bitcoins called a satoshi
If you look at many exchanges , they are even trading at further to the right than 8, and LN has proposed 12 places to the right.
So Bitcoin is not as really scarce as they make out.1 bitcoin continuing increasing to the right , is basically an unlimited commodity.
* No where in the real pysical world can you continue inflating to the right and
the unit still have any utility, where as in the virtual world such limits do not exist.
