No problem. There is a lot to watch out for. Most of the bitcoin advocates will tell you that bitcoin can't be manipulated. Heidi did a Utube post about that actually. Can't be further from the truth. Biotcoin is a low float (because many long term holders are simply holding...they can't lose unless price drops to $20) so that means the very few coins that are being swapped on the open market each day are very easy to control pricewise. Do a little bit of internet research. Wall St is now involved. I have psoted about 5 or 6 items here at steemit "proving" that there is manipulation of price via strategic buys and sells. Plus getting in and out is "obviously" a big pain. You can actually trade bitcoin right now if you have an online brokerage account that let's you trade OTC stocks. The U.S. equity exchange traded "bitcoin tracker" is gaining more popularity every day. Trade volumes are picking up. It offers the same overall returns and even beats actual bitcoin at times (I posted a buy advisory today that generated a 8%+ move in 2 hours). So you decide. Do you want to jump thru hoops to trade actual bitcoin...and "hope" your exchange is there to take your sell order as price is dumping $100 in 5 minutes? Or do you want out in 5 seconds with this? :-)
