Roughly in June 2013 I bought my first Bitcoins. I only spent €10 or so, so it's not really a big deal.
I mean, at some point it would have been worth €2,000 or so (but who is counting)...
Considering there was now a significant drop for basically every of the major cryptocurrencies, there is a big backlash happening again and people finally having there moments of "I told you so". Well, maybe they are right. But on the other side, and honestly I don't know why, the crypto market always has a drop in the beginning of the year. So it might be nothing else than seasonal effects.
And people are right, there is coins popping up for everything, BananaCoin, or my favorite Dogecoin. Coins will in the end only be worth something, if the technology that is used behind is actually useful. So figure out if the blockchain technology actually makes sense for what coins are being advertised for.
Also, make sure you understand the limitations behind the infrastructure, i.e. Bitcoin can only handle 7 transactions per second and Ethereum provides developers with way more flexibility than Bitcoin does. And with that knowledge I am likely barely scratching the surface.
With a bit of research, listening to podcasts and similarly, pick the ones the sound reasonable and play the long-term game, not that day trading stuff that makes you greedy and miserable.
Blockchain and crypto is a big thing, and at least everyone understands that no one has all the answers yet or how it will end up looking/shaping society. But there is lots of potential, and if that potential becomes true (and it has a chance to accomplish that), then I want to see how far my little $$ will get me
