At the moment it looks like the strong downfall has stopped but that still doesn't mean that corrections are over.
Just at the first glance it looks that market is more stable now but this can change any time so it would be wise to use to buy more coins. The correction will not last forever so be prepared when the price start to rise again.
And as what the article stated, those coins that would be able to survive the recent bear market that we are experiencing is just one proof that it was able to withstand this kind of market situation and make the investors trust more the project and then it would become more valuable. We have yet to see what coins will survive the purge as it will prove if they are really worth to be included in the cryptocurrency market or not.
The cryptocurrency system is still very new and fragile.
It would have to go through a lot of adaptations and corrections, in order for people to get a better knowledge of it and how to properly integrate it I to the system.
There would always be coins that would rise a couple of times and then there would be those who would lose the trust of people and then eventually lose its value slowly. Just observing how much the coins have lost its value for this year compared to last year will give us an idea of how people trust the project.
