Today and this week is best to buy bitcoin,
because the symptoms go down are symptoms of rising,
hopefully
Nice spirit ! But look like the system doesn't work like that at all.
There is no system actually, just follow the trend and eventually you will be profitable in the end.
Bitcoin will fall and rise but based on what I have observed which I am pretty sure everyone who have monitored the price well will agree, when the price dump it's a good time to accumulate and you can sell it for profit in just a short period of time as the price will be back up.
The price of bitcoin is depend on the demand in the market. Sometime the reason why bitcoin was falling is because there's a lot of it available in the market. In the other hand when the price of it was too expensive then the possiblity is there is a shortage of bitcoin in the market. And that is the right time to sell your coin and cash out. Because it can give you a huge income.
