If I were to give trend advice on Bitcoin, I would say it's currently a good investment at around $14k USD. That said, anything is worth what someone is willing to pay for it and you can get a piece of the action for as little as $0.02 (Granted it's only one hundred Satoshi) so there is some appeal to the possibility of making Bitcoin Millions.

The greater implications of the meteoric rise of Bitcoin is the possibilities for so called "Alt-Coins" or assets with similar characteristics. At first the flood of "shitcoins" will saturate the market and many will fail, but as coin issuers create more value for their coin (eg SBD and Steemit) the prices will reflect a scarcity/value ratio.

Personally, I see cryptocurrency as an asset based accessible mechanism that is more friendly to the everyday person than the professional investor. If you follow a good investment strategy, diversify, and do your due diligence it has the same opportunity as any stock investment.
