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 still, there is a huge possibility to grow because of the price of altcoin decreasing a lot in the market. Now it is the right time to enter the market and start buying the huge potential coins which will help us to make some decent money in the future.
