to suggest is very difficult because investing with a crypto or altcoin currency requires the confidence of the investor itself and maybe as a little suggestion to choose coins that have good ratings in the crypto market maybe that can be a little for consideration
why is it so hard to believe in a project and coins? we only need to look at the market and see what assets are most popularly traded. after that we can research the product and development that has been done. if they have great support from the community I think we are worth investing there.
