It depends on what you invest in. A solid crypto project should steadily grow over time, while scam projects always end up taking the investors' money and disappearing. Be careful of what you invest in.
We all know that it doesn't work like that every time right?
Cryptocurrencies with good futures might be great but in the end, they still usually die. Investors leaving after getting their profits, bounty hunters sometimes sell their cut after receiving it, it is easy to crumble when that happens. We can't stop people from expecting continuous growth since it is the reason why they are here but they should also know that Bitcoin and other cryptocurrencies are volatile.
