I think the simplest way of growing bitcoins is to purchase some amount of bitcoins and do the trading with some of amounts will be beneficial to grow the bitcoins.
Yeah, but you should be well aware when to buy it and when to sell it, if you know the right time to buy then you can make a good profit by selling it on higher rates.
that it is easy to say. If I knew 100% when is low and high I would be fricking rich now
Well yeah, a lot of people would be filthy rich if they knew when Bitcoin and other things were going to be cheap and when they were going to be expensive.
That's part of what makes things valuable, they can become high or low valued at any given point.
