There can be many reasons. For example, because there is no infinite growth of coins in the market. Experienced players earn both during growth and during the fall

Coins are dropping due to Bitcoin & Ethereum prices are dropping, as these both are king of all coins. There are many other reasons also like ban by government of different countries, negative news in media. With the recovery of market with time, coins will also recover, so just wait & have patience.

There are a lot of them, because everyone sees this as a big benefit and they want to steal money. They earn dishonestly and this is not very pleasant on their part.

The market develops cyclically, and after strong growth there will be a strong fall. At the moment, we are experiencing a phase of a strong fall. But we must believe that soon growth will begin.

I think that at the moment no one should have such questions. The market decline in early 2018 is due to the fact that there was a market oversaturation and a quite expected correction took place. At the moment, institutional investors and large players are planning to enter the market, so they try to squeeze the price down as much as possible due to the altkoins. That is why the share of bitcoin capitalization for the first time in 2018 exceeded the 50% mark.

Prices for most coins went down. I think that this is due to the fact that investors have lost interest in the crypto currency. The market of crypto currency requires new fresh investments of money.

I was in a trading seminar last week and I learned about these cycles, very interesting. Right now we seem to be in the accumulation stage, and it's best for buying as the prices pretty much bottomed..most people buy during the parabolic move, that is a big mistake.

In my ideas the coins have fallen due to the ICOS process encountered a difficulty in the language barrier is typically the china coins. Plagiarize and do the same thing and promise a lot like collaborating with big companies but failing to give me evidence for example. Another problem with ICOS like NEO is that they are Chinese It claims to have artificial intelligence applications but does not prove it. So how can investors differentiate between real projects and virtual projects? in addition the BTC market devalued the affected coins and down by psychological factors.

One of the reason why altcoins are dropping because the btc does. Btc is a kind of barrometer in the market. It dictates the price. The graph on the cmc is all similar on btc’s graph.
