Hi there what happen all altcoins and bitcoin is dumping but why? Im panic about that and the coinmarketcap still dumping this is the end of cryptocurrency? Anyone knows about this? A litle worried about what happening now.

I think it is affected with Mike Bell (JP Morgan) pronouncement that cryptocurrency could ban by the government.
Many investors may have panic about it.
Bitcoin has been branded a fraud by the same person years ago but look btc now.
Well there's a lot of news going around the ecosystem for the past 2 days that really cause the market to crash. Governments are waging war against it, but I'm sure that we can stay afloat in the next coming days. This is not a long term effect on the market.
We can't really control how the price will moved. Sometimes it will not go on our favor because of the FUD going around. Its just normal to see corrections happening from time to time so that we can moved even to a good direction. Another bump in the road, the logical option is not to panic sell, hold on your coins and come back after 3 days. If you constantly checking the price of your investment going down, most likely that your decision will be clouded and sell everything.
