Just found out that Bill Gates' networth,$86B is the market cap of the top 5 cryptocurrency, including Bitcoin and Ethereum, combined! 

Goldman expects that the price will not go much higher and, in fact, believes that it may decline. 

"Wary of a near-term top ahead of 3,134, Jafari concludes. "Consider re-establishing bullish exposure between 2,330 and no lower than 1,915."

What do you think?

"Mark Cuban has attacked Bitcoin on Twitter, claiming it is not a currency, it is a bubble, and that the whole system of valuation concerning it is wrong. But is he right?"

His comment caused the Bitcoin price to drop before it hit $3000.  He said Bitcoin's increasing price now is a bubble.  What do you think?

Ha ha..... mind my own business, but I am really curious.

Here is the wiki on him:

I just realized that he was in the documentary. "Bitcoin Gospel". the documentary which converted me to become a Bitcoin investor.

My concern is that if Bitcoin can be an effective medium of exchange tool? 

The reason why I asked is that there are fees associated to each of the transactions and the fees are increasing day after day, so it gets to a point that it is no longer justifiable to use Bitcoin to buy smaller items.  Higher fee becomes required as low fee transactions will be placed in the unconfirmed bucket for long time, if not forever, as no miners are willing to include them in the block to validate it.

How will the high transaction cost impact Bitcoin usage and price in the long run?  I would rather to see the future price increase is due to demand in the coin circulation than due to demand from speculation. 

Please provide your feedback.  Thanks.

Could someone tell me how many Ether coins we will have in 2020, 2035, and 2050 and their projected corresponding prices?

I am wondering if it would have the same price as Bitcoin?

Russian is planning to have its own version of Bitcoin backed by the Sberbank.   

"Sberbank CEO Herman Gref has “agreed” on the development of a Russian national cryptocurrency with the country’s central bank.  Sberbank is Russia’s major state-controlled bank. In unofficial reports from local news aggregators, the so-called “Russian Bitcoin” will use Sberbank as its base and will be “the only cryptocurrency freely available for sale and purchase” in the country. “All other [cryptocurrencies] will only be available via exchanges or trading platforms,” the Telegram news channel DeСenter reports Friday."

What type of impact(s) will this have on the original Bitcoin?  Would the Russian Bitcoin survive?  Would the original Bitcoin be treated as a lower "second tier" crytocurrency in Russia or even in the world?  Would the original Bitcoin value goes down? 

What is your thought on this?

Could someone direct me to tutorial videos on the subjects that a newbie can understand?

Thanks.

Hearing some news on soft fork/hard fork and Bitcoin Core and Bitcoin Unlimited, but is Bitcoin Unlimited being traded right now? 

What is the status on the soft fork?  Has it been implementing yet?  If not yet, what is the expected launching schedule?
