To invest in ICO, I want to start from the $ 500 amount? Can you give me advice?
I suggest you diversify your $500 amount into different coins/tokens.
Invest some on bitcoin and top coins for more stable growth. Then put some on ICO that you think have potentials. Be careful on ICOs as much of them are either scam or non potential. Only few ones fave potential for growth. Join their discussions to get more information and see if the dev team is serious on the project.
In here you cannot be able to get an exact details how to face ico. You have to find a good ico. be sure to prevent scam icos. So i recommend to ask your friend or find a ico project in ico rating website. in addition to that you can search from youtube how to face ico and what is the procedure of most icos.
