Yes there is still hope. I too am optimistic in a few months to come bitcoin and ETH will recover. But some alts with no usage and no strong community will end up dead in the end. Too many competitors and same product quality makes it hard to decide in which coin to invest. I often choose ICOs with already existing product and company. Unique product and usage. Its worth the gamble, for my opinion.
You need to find out if you hold one of the valuable coins that causes if you have one of the scam coins then you have to worry about bringing these items to your portfolio and removing them.
