I've been reading through this forums for the past few weeks and all I see is "this coin is dead" or "everything is a shit coin". Is there any alt coin with potential to invest in or is it only bitcoin?
To be safe, you can buy from the top 2 to 20, but if you want to do more in-depth research on the project you are going to invest in, then you can choose an altcoin that is not even favorite, but you are sure that in the long term the progress will be good.
You are definitely right about that, top altcoins investment is safer than investing in other cryptocurrencies. They have more potential to get up in the future than other currencies. To make research about the project which you want to invest in plays also an important role. We should be aware of the project and then we can invest in this project. Sometimes we should be patient, that is why most top altcoins are the best choices for long-term investing.
