This is a good point adultcrypto since we don't need to have faith from the start and we could even be somewhat bearish, and in some sense, if we try to figure out our position size in accordance with our level of doubt or our level of bullishness, we can adjust our position size to become greater in the future if we become more bullish in the future.
Being bearish would allow you lower your expectations and when it turns bullish, the joy would be stronger. But being too bullish in your expectations may expose you to investing beyond your capacity which would also make you unable to hold for long.
Bitcoin being bullish is the more reason why people will want to invest in it. and even if people get overly excited and buy aggressively they will surely get their profit in the long run. But people should not overly get excited of Bitcoin volatile nature and invest above what they can afford to lose otherwise they will still sell off their Bitcoin without meeting up their target. And secondly you don't need your mind to fluctuate because of bear and bull season, by lowering your expectations in bear and having joy during Bull season. We all knows that Bitcoin will always have bear and bull season and that should be a more reason we should keep investment without looking at the appropriate season and time to invest.
