Market correction can happen anytime and this is one way that we can avoid the so-called BIG BUBBLE from happening or the collapse of the whole cryptocurrency market. Correction can be painful though specially for people who are hodling on to their coins or tokens but it is just a matter of waiting eventually things can get better...assuming that we are not really dealing with shitcoins in the first place. A project with a good concept that is really providing solutions to some real world problems and manned by people who know what they are doing will always go up sometimes it is just a matter of time. Yes, this is partly done by the market to wipe out those shitcoins that are offering no real value to the market and are just here to make some money via pump-and-dump technique.
