I think we just need to give these crypto currencies time and patience. Right now, i see alt coins that build their blockchains around internet servoces like gambling and content. But i think given time, projects will rise that we can eventually use crypto currencies to buy food and services we actually need to survive everyday.
Yeah you are right we should give time to cryptocurrency and there is no doubt that it will take over the market in the future. We will definitely use cryptos in our local market for our daily needs. Using our cryptos is the actual aim of bitcoin and not earning money. With the passage of time people will enter into crypto world and the use will also increase. I already use my coins for my daily shopping.
