It is difficult to predict the price movement in such a long period of time. I can only offer to buy in the area 15-17 satoshi, a large customer is tracked at this level. This is a very strong level of support with a history since 2014.
I think you need to start buying by 30-35, there are also quite strong purchases, besides the lower price may not be allowed. But you should take with a short stop, if your version is correct.
