The biggest challenge for any crypto project is mass adoption and for various reasons many people still prefer the traditional method over blockchain technology.
They will prefer it and it will take a long long time before a transition will start.
People prefer to use the traditional method of paying which is the fiat currency because they feel comfortable with it. Another one is that is the currency that all of us are accepting unlike crypto that only a few are accepting it as of this moment. I agree that it is the biggest challenge right now and its normal too that transitioning from another currency to another will take some time.
So, which crypto project do you know that has a real plan to expand globally and increase the mass adoption of your project and crypto in general?
Bitcoin and those top coins as well but Bitcoin is the top pick with this.
