Ask yourself: are the assets you're buying actually 'investments'? Because when you invest, you hold that certain asset for longer amounts of time. An investment isn't something you just immediately sell the moment it drops a few points.
As for more dips, no one knows. But tell you what: bitcoin has been the best investment you can make since the past decade. But was it's price chart just a straight upward trend in 10 years? Hell no. There was always price drops, even as big as 70%-90%. If you can't handle price drops, then 'investing' isn't for you.
Well said, an investment is not something that we should expect a big returns within few weeks, months, this is the perception of many investors hence every little dip leads to a huge sell off by the weak hands there by crashing the market even further down,
long term hodl always pay off if you have the patience to do so, ( holding of good and solid project ofcourse and not some shit coins)
but unfortunately the majority of investors are short term investors who are just looking to make quick profit within the shortest possible time.
