If you are buying and Holding for years I would suggest a little more research. I agree that this is likely to work for the major cryptos but there is so much rubbish out there that all profits could be wiped out by buying a crap coin that goes to zero. Money can still be made in these but I don’t think they will be profitable longer term. So I would stick to the top 50 or so, or do some. Or do some more research.
