Altcoins are good now a days for investment .how can we increase our income by investing in altcoins?
Investing in altcoins is a full time job because of that my advice is to approach altcoin investment with extreme caution, and be prepared to do a lot of daily research.
1) Make a habit to go on coinmarketcap every day and monitor the price of the top 10/20 currencies
2) Explore the community of the coin that you like and be sure they are active.
3) Train yourself to spot the scams: HYIP, Ponzis and so on.
4) Learn some technical analysis and trade on an exchange.
5) Research, research and more research!
