Sure. It is not guaranteed to go up, but it is quite likely that after a full cycle of continuously buying bitcoin (and perhaps even aggressively buying) and even 5 years you are going to start to feel that you are making quite a bit of progress, even if you might not be done accumulating bitcoin yet, unless maybe you had been able to front load your bitcoin.
Even with you MusaPk, you seem to be over half way through your 5 year journey, and even getting close to 3 years of buying bitcoin.. so that must feel good.. even though surely some guys may well have had got a slow start in their bitcoin investment instead of investing aggressively from the start (or the start of their forum registration).
Yes it's feels very good to be in bitcoin specially if you are accumulating Bitcoin for around 2 years and you see your target is very near. I do agree that my start was slow but once I figure out the advantage of keep on investing in bitcoin for longer duration, I don't miss any week now in which I don't invest in bitcoin. I wish I would have been investing since I registered here but it's useless to think about lost opportunity. Best is to take advantage of what opportunity is at your disposal.
