My biggest problem in trading is that I was too brave to buy altcoin at a high price, and because of that I often lost my btc, even once I lost 50% of my btc when I bought altcoin at a price far above ICO.
So please give me feedback on this, what should I do?
If you do not want to buy altcoin or to used your own money to deal with new altcoin you may consider on appliying on a signature campaign alts, all you need to do is to support the project so that you could earn new token that you could actually trade afterwards. It is a good thing because it also help you to learn things about ICO project and new crypto-currency projject.
