Pls not all cryptocurrency has the potential for one to adopt so you need to be specific and use the word bitcoin.
Bitcoin is a biggest cryptocurrency but it is not the only cryptocurrency so I see it is fine to discuss about cryptocurrency adoption generally. Bitcoin needs altcoins too even many altcoins are scam. The cryptocurrency market should not have only Bitcoin and altcoins are necessary for the market.
My reasons for adoption of bitcoin is that.
1. It gives financial freedom and can be used across boarders without a third party.
People will have control of their bitcoin if they use non custodial wallets. If they use custodial wallets from like exchanges, gambling sites, they will not control their bitcoin.
No control, no chance to have financial freedom because they can lose their bitcoin, capital anytime.
Reminder: do not keep your money in online accounts2. I also use it as an investment and a store of value. As an investment, you will see it that bitcoin is the most valuable investment that one can make a good profit from, if you can hodli you bitcoin for a long term. For store of value,because fiat is depreciating in value daily due to inflation but bitcoin is inflation resistance.
Consider Bitcoin as an investment asset and as a store of value is the same. You should not invest in Bitcoin if you see it is not a store of value. Bitcoin itself is inflationary because new bitcoins will appear with each new Bitcoin block.
There are already
19,444,675 BTC mined by miners and already exist in Bitcoin circulating supply.
The curve starts to be flattened out and not many bitcoin will be mined from new blocks in future.
3. Bitcoin is the future gold because soon people that have bitcoin will be the richest or most wealthy people in the world as long as they only keep on accumulating their bitcoin.
Not all people who have bitcoin can become rich, millionaires or billionaires. It depends on how many bitcoins they have.
