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.
theres no trading strategy for me, what important is you know the basics in trading, you can also buy books so that you can understand it well and sometimes you can predict what will happen next to the coin that you have, it is good to know that, because many of other traders can analyze what will be happen in the coin.
