Whether you'll be successful in trading Bitcoin depends on the preparations you make. They either support or undermine your efforts.
No one will ever undermine your efforts if you never did in the first place, knowing about bitcoin is not a difficult task to do but people don't want to give it the time and attention it requires to pass through the learning process, thereby seeking for a shortcut to learning bitcoin.
First, make sure you have enough money saved.
Not really necessary, you can start with little, there's a particular pattern called DCA whereby you can go on accumulating bitcoin by weekly basis or monthly after carefully studying the trend on the move of its price, whereby you only set in to position for buying the dip.
