It is best to start your investment in Bitcoin and top coins to reduce risk. Other less known small coins can go out of business in a bad bear market like this or may not recover back to highs.
I think that the correction of the cryptocurrency market is taking place today. And most projects that do not have a final product or are not interested in society in their idea will leave the cryptocurrency market.
It looks like many of the projects will leave their projects and the developers looks inactive for their project but I think it is because of the current market that is why they do not come online and want to start listing and other work after the market come in bull condition. Many of them work offline only for the product.
