Next to Bitcoins there are several different other crypto currencies like DASH, ETC, ETHEREUM, LTC, XRP. Do you believe in them? Are there any Advantages and/or disadvantages?

ETHEREUM and XRP and Dash are good to compete with BTC, about ETC , i don't think it has a good future.
LTC is a simple clone of BTC, to me it's a shitcoin .Nearly no developments for years, why does it still in top 5?I don't understand.
Probably because the chart is always stable and has investor confidence this makes the coin still survive.
