after all there have been many old projects that have proven progress, if you are still looking for new projects which of course it will be difficult for you to research them, then investing in old projects i feel is not a problem, because so far even though their prices have dropped but that does not mean the project will die because there is still a very good recovery phase for long term investment
Indeed! There are many projects before that are still running until now , yes some of them do not have a good or great prices now but the thing is, we cannot predict what will happen in the market , maybe soon the coin price will be huge, you may also consider those projects that has been introduced in the market even it is already ended year or years ago, as long as the projects has a possible output and also has a good market value when it will be listed on.
