I am not skilled about altcoin investment but I wish to have little experience to do some kind of portfolio diversification. All I do is bitcoin long term investment and it gives me peace of mind because I wouldn't need to be checking bitcoin everytime nor do I need to close monitor my portfolio.
There is no doubt that Bitcoin is the king of all crypto currency markets. Most of the people who have good capital invest in Bitcoin, and for the long term it is a good investment. I think investment in altcoin is a good option for people who have less capital. Where with less investment they can earn a good profit. According to my opinion those who have more capital should invest in small coins along with Bitcoin, because this way you can increase your profit rate. There are many good projects in the market right now where you can choose good coins after research. So altcoins should not be ignored. There are many coins that have the potential to give a good profit in the future.
