Yes I do believe in cryptocurrency still as it will liberate us in terms of transaction and other monetary purposes. For instance, I am living in a corner of the world. when i want to buy something from another corner, I won't have easy access as banks the only accessible and known means create unnecessarily hassles. So with cryptocurrency, I will have easy access to whatever I want to buy no matter from where. Concerning it will make us rich, such thing will not happen in cryptocurrency overnight unlike in the past. It is investment like in other sector. It takes time.
