Yeah... this happens all the time. Crypto-currencies are highly volatile, at least when compared to the other investment assets such as equities, mutual funds, bullion and real estate. And that is their attractiveness. You can either gain big or loss big. A single trade can make you a billionaire, and if you are unlucky then you can become a beggar in a single day.
Indeed, I've had a few trading accounts wiped out with silly investments.
Now my main play is BTC and the other larger cap cryptocurrencies, ETC, ETH, LTC, ZEC and so on. Been caught playing so many 'shit'coins in the past, it's not worth it.
Also learned that position sizing really helps, don't go all in on one coin. This is another thing I've learnt the hard way.
