Bitcoin - Useless, worthless.
Cryptocurrency - Now this is the real deal, this is open to inventions, upgrades, solutions, efficiency.
Let me just emphasise the last word, efficiency. The one word that every company today is built on and embraces, with efficiency comes money. There is no hiding from that, if a crpytocurrency provides efficiency for a sector, it has value, it is that simple.
Humans have evolved to hate change, it's nothing new that people dont like an internet currency, but the truth is, the world is becoming digital, and currency needs to make that transition, it is happening and it will be succesful. There are too many Intelligent investors for it not to happen. Sure people are abusing the market now, but wait until it gets regulated, that's is when the big boys are coming in.
The real issue is, everyone buys bitcoin hoping to make money, the smart money will go into the Altcoins with real value. Stay away from bitcoin, it is obsolete and will die sooner or later. Dont stick with it because you hate change.
