I disagree, as an investor the most important part of investing in bitcoin should be patience, timing comes second. Timing only plays a major role or works when you're a trader or speculative investor, investing for just a short period of time. For example, we have bitcoin enthusiasts who did invest when bitcoin was around $400-$1000 (you can call that perfect timing) but today due to lack of patience most of those investors don't have a single bitcoin due to impatience some might have sold at lost or little profit. As it's commonly said, "investors don't wait to buy (timing), they buy and wait (patience)".
