Nothing is free in this world. My friend keeps reminding me of this. Especially when you want to be rich there is always boulders and walls in your road. That shouldn't stop you from taking that road though. Bitcoin especially has a pretty high risk going with it. Investing means to put your money in the hope of something good in return. However, it's not guaranteed. Bitcoin isn't any different. Putting your money in it has it's risks but you gotta be ready for it. Whenever I see the word "free", I always take it with a grain of salt. Don't be gullible.
