Learn to value coins in BTC. Ether aside, Bitcoin is the current primary currency of the crypto economy (i.e., its what you have to use to buy most altcoins). Those new to crypto tend to value things in dollars. Meanwhile, even seasoned cash traders value coins in dollars. However, enough crypto traders will value coins in BTC for it to matter. If you aren’t aware of the BTC charts, you won’t be able to properly understand the trends everyone else is analyzing and reacting to. You don’t have to make getting more BTC your goal, but you must have the BTC prices of altcoins on your radar. There are times when all coins move up, but altcoins steadily lose value against Bitcoin. Those who know will be the first to dump altcoins for Bitcoin; this will set off a vicious cycle that can result in the stagnation of altcoin prices.
I have been using Coindex for a long time now and am constantly impressed by the time and care Josh and Cellaflora put into the project. There is an emphasis on perfection and testing the app's features before release and this has amounted to a polished and irreplaceable part of my iPhone. Coindex will always have a space on my dock and can't wait to see what they add next :)
You could try this instead: Develop your own day trading strategy with indicators and rules that you understand and hold yourself to. Then read the news, but read it with a grain of salt — and try not to make trading decisions based on rumors that might be debunked the very next day. You shouldn’t buy just because you see the price rise and fear missing out.
Don’t be greedy. No one ever lost money taking a profit. As a coin begins to grow, the greed inside us grows along with it. If a coin increases by 30%, why not consider taking profit? Even if goals are set to 40% or 50%, you should at least pull out some of the profit on the way up in case a coin doesn’t reach the goal. If you wait too long or try to get out at a higher point, you risk losing profit you already earned or even turning that profit into a loss. Get into the habit of taking profits and scouting for re-entry if you want to continue reaping potential profits.
