But make sure they are good projects, some bounty projects are better dump off than holding them, you have to find that out yourself, example of good bounties was Tokoin, Gowithmi, Sero, TemTum, they are worth holding, thanks
I can't say about other coin you mentioned to be good project but that of tokoin, it isn't performing as expected. It is dumping lately despite other coins hodling the tides. I think it was suppose to be a good project from IEO to distribution but it has dropped in price and also volume of course.
