The best thing to do is to have plan. Planning is essential in all aspects especially when it comes in trading, because when we do not have plan, there are more mistakes to come and have a big loss of money. The other think you need to do is to learned how trading works like bull market and bear market. Bull market is just simply a bull but when we give them a deep meaning is symbolizes price are rising, because the bull acts his horns up while the bear market swipes its paws downward, so that it symbolizes as by falling prices.
He already has a plan, to start trading with some part of his saving. In trading timing is everything, I would suggest to OP to start with some small amount and to try to sell at top, or at least close to top, and of course to buy when price is at bottom, or at least close to it.
Of course nobody can't predict top and bottom, that's why you have more than one sell order, and of course more than one buy order. You check from time to time your orders, if they are executed you make new ones. We never know will price change direction, we don't know where is heading, so I suggest newbies to always have some dollars and bitcoins on a side, if price surprise you and do something unexpected you need to have some bitcoins to sell, or dollars to buy, depending where price went.
