Waves is still a undervalued coin! It has a great potential to grow up with bitcoin in the future. Russia is plans some nice stuff for cryptocurrencys and theyre not going to ban the ICOs like China. Theyre looking forward with cryptocurrencys and they want to integrate crypto into the normal peoples life.

Coinmarket does update the prices immediately as compared to worldscoindex and if you see the websites, the prices are updated in real time unlike the other site. However, sometimes there isn't much trading volume on exchanges and hence the prices are shown after gaps of 3-4 hours.

Worldcoinindex seems like a copy of coinmarketcap.

The reason why worldcoinindex has a higher bitcoin price is that it only lists markets that trade with USD, nothing that has foreign currencies involved. Coinmarketcap takes the weighted average of every single exchange, whether they are located in the US or outside.

Right now the Chinese exchanges are significantly lower priced than US exchanges.

I would recommend using coinmarketcap. The interface is better and you have more options imo.

In my opinion both of them have their advantage,
For example like mjglqw said.
Coinmarket collecting data for more than 400 exchanges and worldcoinindex only 18 exchanges.

In general coinmarket has a lot of data and price change which mean they can make an average price/percentage from whole exchanger.but you must know that a small exchanger usually have a big gap between their buy and sell.
Because of this,it can change the result in whole average data.
Unlike worldcoinindex,they choose to collect the datas from poppular exchangers.which mean they are more specific in collecting data.

Which one is the most accurate ? It's depend on your situation.

The cryptocurrency price shown on both sites are the average price from the exchanges they're getting their data on.

Lets put bitcoin as an example.

On worldcoinindex, they're only taking data from 18 exchanges. Whereas on coinmarketcap, alot more than that (400) since not only they're taking data from more exchanges, but also because coinmarketcap is also taking data from different pairs like BTC/JPY, BTC/SGD, etc.

So to answer your question: coinmarketcap is more accurate.

When I was talking about bitcoin with my brother my grandma heard bitcoin and she thought I bought a sheep because "coin" and "sheep" have similar pronunciation in my own language  I didn't even try to explain it.

Just work for a campaign you'll get like $300-500 good money. hahaha

My father invest in crypto all days read newspaper of crypto

Well you kind of gave told them the big misconception about cryptos and they got you on it.
Banks do more then transact our money, they do give loans as well. Cryptos won't take their whole business, just a portion. The most unfair one.

However, it is important to note that most banks give such bad rates that it doesn't even cover the inflation. Try saving some swiss francs and you will see that they will give you a negative rate for saving. Their savings are a scam as well, but it doesn't really have to be. Loans are just a smaller part then they manipulate to be, but they are a real part of the economy and will be there with cryptos as well. With cryptos there will be no inflation eventually and a very small one until then, so many many banks will fall.

Yup, I took the plunge and invested little less than half an ether. Probably wouldn't have been too pushed had it not been for the fact they pay dividends the 15th of this month.
