Btc dumped hard after the fake news of goldman but after their representative told that news was fake instead of recovering its value btc still not recovering its value what is the cause of this bloothbath
As soon as BTC failed to break the $7500 mark, it was due to fall again, I believe it was due to Technical Analysis (trader's tool) more than anything else.
As for the altcoin market, it is more of a long process now, started several months ago, but now many believe the market is coming to the toughest times, the same way as the Internet frenzy at the end of the 90's... Not really unexpected though. Just hope you guys were able to make some profits from it last year, especially with Ripple, NEO and Bitcoin Cash.
Until 2019, the best advice is to be very careful, but I still strongly believe some Altcoin projects will be successful. Look for IOU for instance, promising project >
