There are good and bad altcoins in the market. If you go ahead with all the good and bad coins but you cannot protect yourself. If an investor goes ahead with the best coins then he will definitely get success. So it is always better to proceed with service to make yourself more successful. I will never go with shitcoins to invest I will always go with the best coins to invest. Even though my profit will be less and I will get less return, I always prefer to stick with less risky coins to be safe because I don't like to take more risk.
