Cryptocurrency, will it bounce back to the heights that it once was again? Would it be wise to move in and invest now? ?

I think its more of a safe haven although it's purely speculative (at the moment).

If you want to catch the "next boom"/FOMO, why not just earn them? It's the newest way to obtain crypto nowadays. Don't need to buy them. I spent about 10 minutes doing paid surveys like the ones from OpinionWorld and was rewarded with crypto.
Cheers!

As you can see, crypto hasn't been doing well. The increase shortly after the fall is known as dead cat bounce (quite morbid) -- if you drop a dead cat, it will still bounce, however little. Subsequently there hasn't been any increase. It is much safer to go with 'traditional' investment medium rather than hoping on the bandwagon (marijuana stocks/etf, crypto, trending tech stocks...) where any increase in prices are mainly due to sudden interest. Personally, I would only enter the market only if I have sufficient degree of certainty in its outlook. Until then, I would refrain from cryto.
