Their is something I understand for bitcoin purchasing and also bitcoin holding, the most thing  that is very important with bitcoin investment is that it depends on when you will release your bitcoin, but one of the parameters that can lead the buyer or the investors to the profiting aspect of it is through timing before you buy, I have heard many conversations that relates the appropriate time someone should purchase a bitcoin but from my observation I don't think investing in bitcoin have actually period you can invest.

What is most important for bitcoin investment is that Bitcoin investment have to do with research and timing before buying so that you will not experienced any loss, so in actual sense it's cogent to purchase when bitcoin is dip so whenever the market is of positive they will be a profit and something of that kind should happen when you have in mind for one year duration or six months duration of investment

Mostly what keep investors behind of not making profits is that they don't calculate a time and for you to buy at dip that means you have scrutinised the market, and it's a priority of buyer to investigate and examine before buying bitcoin.
