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)?
No particular amount as long as you know how to trade. Even a little capital will do, the most important is the skills to earn with trading.
