Crypto Currency attraction

()
I had not heard about crypto Currency till 2017. One of my friend introduced me about crypto currency. I started searching the importance of it. Now I feel as I am addicted to crypto currency and everyday I am working with crypto currency.
some times I am asking myself, am I doing wrong spending time with it ? is it good to spend most of the time learning about crypto currency? most of the time I get answer negative but maximum time I get answer is , it is worth to learn more about crypto currency and this is good time. Because , I believe, someday I will be ahead of my friends who say I am wrong today. Crypto currency is going to control the world one day. If any one say today crypto currency is buble but the time is coming , they will realize and they will try to hold crypto currency for daily transaction. It is my personal belief and observation that, currency has got developed crossing many steps from the beginning world started transaction. As the technology is controlling the lives of human in the world today, it is much worth to say, that crypto currency cannot be ignored for transaction system any day in the future.
It is encouragement for all crypto holders that, we have new transaction system in near future. Hold all crypto currency and have patience.
