when price are faling is the best time to buy some chip altcoins with btc and wait for one or two month to get you double profit .
Not double, 100x. Oh man, can you really double your money so easily? You say it so easily, but it's not so easily possible.
OP I suggest you to familiarize some experienced traders here, yes, you can find almost every successful man in bitcoin here because of this amazing forum, ask them advices, what they think, also look people's panic on forum and it will help you.
This is a very good advice for someone who would want to get into serious trading. It is not really easy to trade and if you do not have some strategies, you will just be messing up your trade anyhow. If it was that easy, then most people would be making a whole shitload of money right now in trading. You just need to have a strategy and to me the best is, never hold a coin for loss for too much.
It is better to have little loss of about 5% than having a 100% or more loss. If you buy at a position and then it goes down even more, then sell and buy at a level you are sure it is best unless you want to do cost average anyway.
