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)
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.
Don't want to rain on your parade pal but, i think you really should research just a little bit more about bitcoin and how it works because obviously, you still do not know it that well yet.
All the problems you have mentioned are not real problems of bitcoins. I would've explained it if other people haven't already did. But since they've already said the things i would've said, then I'll jist give you an advice.
Do not ever believe everything you see in the internet.because not all the things you see are real. Better to confirm things first yourself before speaking about it at any matter.
