I didn't getting the point of cryptocurrency market going down from past 3 weeks.
It's not been down for only 3 weeks. We're already down for several months so you really don't know what's happening do you?
This the right time to buy more or existing from all my investment in coin and tokens.
Yes, this is the right time of buying more coins that you wanted to hold for long term or short term. Every coin has it's discount so grab it now while you can.
