Know your time frame before you enter!
What time frame do you have in mind to reach your target?
Based on the time frame you're trading you should put a target, it's all about having a plan before you enter the trade. for example you could trade on the hourly. If you trade on the hourly then look at the 1 hour candles. Most of the time this could net you around 10-20% trades. Now if you would trade on for example a 4 or 6 hour time frame you are more looking at the 30-100% gains. because you're looking at a longer term than the hourly.
What about the really long term time frames?
Now we're talking about the Daily, 3 Day, Weekly and Monthly candles. Those time frames we're not talking about 100% anymore, we're talking about 3x - 10x and even higher.
Got a brilliant entry on the low time frame can I change my view and go for the long term?
Yes you can do what ever you want with your coins as long as you stick to your plan. Make sure you won't sell too soon if you're in for the long term, however if you're in for the short term and it hits your target but it still looks very bullish to you then it's okay to hold on to that coin and ride it up, no one can predict a top. Just make sure you take some profit off the table while it's still going up.
