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.
You make half valid points, like when you say it's a turtle compared to other coins, well known this first of all, your transaction will get confirmed sooner only if you pay more transaction fees. Because at the end of the everyone wants profit, your low fee transaction will only be accelerated after the high fee ones are completed.
Bitcoin sadly is not used for hugeass purchases at the moment by most of the people. Can you explain me how can one clone your bitcoin, or do you mean a bitcoin debit card? Well I guess I haven't heard any one having issues with it except for that of the fees.
