don't get happy too quickly. it's an amazing investment but don't expect insane prices any time soon.
it will be much better if the growth comes spreaded over the years.
It's not going to explode, we still have time for a while, whales are still filling their portfolios with cheap bitcoin while peasants mentally masturbate about buying or not and delusional FUDsters keep shitposting because they already sold.
I wouldn't say "expecting" insane prices soon is a good idea, but I would likewise caution that claiming "It's not going to explode" is just as shortsighted.
BTC has blown through expectations on more than a few occasions in the past. Buy carefully but don't discount the very real possibility of this train pulling out of the station in a big way at any time.
One thing is certain: It won't be steady growth over a few years. It will get choppy along the way.
