Don't panic mate. This is just a correction after the strong rally of last year and this may bounce back soon. Be patient to wait for the market recovery and invest today as you can buy it at lower price.
Yes you are right. We should hold our coins and be patient. Bitcoin trends now starting to move upward so i don't think cryptomarket will end now or even for the future. The cryptomarket trend will goes down and up. And that is normal thing happened always but never worry because it will end up growing again.
