What is happening with bitcoin right now makes us worth hoping for a lot, an increase of more than 15% in a week makes a bull run happen soon, I believe in august the price can reach ATH so holding on is the most profitable option.
But we're already in August. 
Bitcoin to reach another ATH has to surpass the past ATH that we've got. And I agree with you that holding is always effective as it is. You just have to accumulate as many bitcoins as you can or if not a whole bitcoin since it's becoming expensive. Try to catch in decimals until you see your holding grow overtime.
