i think that Investing for the long term in an altcoin is good idea, but you must clearly know on which altcoin you are intending to invest in you have to do a search on that because not all alts are a long term investment. only few of them may make it
Yeah that's true. If you want to hold a coin in long term you should research about the coin so you can't avoid losing your money. Make sure that you invest in a good project that have a potential to grow.
Not trying to tongue lash any Alt, but truth can be bitter sometimes but it does not mean we cannot say it. There are some coins that should not even be looked at when considering investing. Personally, I would not even bother holding a coin like XRP, (you can scold me if you want), but considering the fact that it is a centralized coin and that is one coin that can burst anytime, I would rather just be doing my short trading on it.
I only picked on this because I had to lay some emphasis, XRP is not a shitcoin but for me, I do not like it. You should look out for undervalued coins with very good projects to back them up, those are the kind of coins that would end up being useful and also stand the test of time in the long run.
