Hey there!
I would like to ask you what you concider a good amount of bitcoins for daily short term speculations. How do you think what is the good number for beginers / advanced / experienced traders? Or maybe it if better not to short and just buy some of any good alts and wai for a pump (like some days or weeks)?
Much better to short trade on alts, also it depends on how much are you willing to risk, as for me started at 0.01 btc for short trade. I have a target price of 0.11btc and when i reached that amount i withdraw then start at 0.01btc again. Not easy though you need to focus on what alts are you going to trade.
This kind of trading takes a whole lot of studying, dedication and so much idea about the altcoin market. It is of course very profitable if one can thread that part and can also be very risky as much as it is profitable. However, with a good level of short term trades knowledge, one can make more profit than losses.
You will have to wait and you should identify amount of that you have in the savings that you are okay with this. Most of the value goes the down stage 80% you will be able to have the normal life. After this you will be able to start the trading and be sure that you are aware of this about the trading and the risky about the rules of the trading and the investing.
