It sounds as though you have 0 understanding of how Bitcoin works.
I think there are two huge problems concerning the Bitcoins future use in daily life.
1) Slow transactions
Its a turtle compared to most of the other coins, why should we choose Bitcoin? We actually need real time payments (as we already have them in real life)
Bitcoin transactions are INSTANT, it's just confirmations that take time which shouldn't affect anything in a stable network environment. Plus this won't be an issue
at all with the Lightning Network.
Regardless, all Bitcoin payments ARE real-time.
2) No reimbursements
Paying using Bitcoin (or other cryptocurrencies) can be really really stressful.
If I make mistakes in sending bitcoin (and people make mistakes all the time) I wont never get reimbursed in any way
its not the same with FIAT.
If someone clones my credit card I have some chances to get my money back
what about bitcoin?!
At the moment, its impossible that Bitcoin or other cryptos are going to replace FIAT money in every days use.
Moreover, some more modern currencies have a better technology.
If we really will use cryptocurrencies in daily life, why should Bitcoin be the best coin to use?
This is the key question, because if we wont use it, Bitcoin will be worth 0 and not 100.000$ as someone says.
You can't make any mistakes in sending Bitcoin in everyday real-world transactions. You basically scan a QR code with your phone that the merchant gives you and then press Send.
If you make a mistake copying & pasting an address on the internet you're an idiot. If you choose to type the address instead of copy it you're an idiot and shouldn't be using cryptocurrencies.
It's literally impossible for a normal person to send money to a wrong address.
Here's the thing, someone can clone/steal your credit card and you can get your money back, but one can't steal your Bitcoins as long as you use a wallet password.
Bitcoin is the godfather of all cryptocurrencies and therefore it's at the forefront. It has by far the largest market cap and it's what everyone will use regardless of which 'better' coin comes along. That has been the case for years now yet nothing has replaced it.
We are already using it and it will continue growing, it's unstoppable.
