Crypto-currencies, in particular Bitcoin, is a good thing.
But very few people (I would say less than 1% of Baby Kingdom users) truly understand. When one doesn't understand what he/she buys, the chance of losing money is much higher.
Making a clone / copy is easy (even if you don't know how to code, you can hire people to do it for you), but creating a full scale ecosystem such as Bitcoin is extremely difficult.
