BTC price is more/less stable now, around 670 - 680 USD. BTC price probably willl not go up in next two months.  

The main problem will be BTC transfer time. Which customer will accept buy fried chicken today and receive it tomorrow, because BTC transfer time can be up to 24 hour or more ? At current BTC development stage, online buying have problems. 

Actual benefit is that you invest your money in advertising, and get nothing back. Only very large companies can invest thousands of USD in Web ads and may be get something back. 

This can be reason why Bitcoin price go down from 750 USD price level. $22 millions in Bitcoin market can make some changes in the price. 

Litecoin is alive, but it is just exception. Probably small users group use Litecoin, much more use Bitcoin. Also most popular sites use only Bitcoin. 

Probably better try to invest in Forex binary market, it is much more smart way to make profit. 

Dice bot can automate gambling and make you win faster. Plus you can enjoy how software work for you.

Major worldwide financial crisis can not be, all markets are segmented. Financial crisis can be in one country, but not in all countries, it is not real. Even in one country financial crisis can be as very rare exception - all central banks in each country take care of such things preventing.

Bitcoin and other cryptocurrency demographic data do not have value, BTC market is not expanding very fast. As you can see - large Web companies, like Amazon, do not implement Bitcoin as payment yet. 

If you even try to mine with normal computer, you will get just some coins. For real mining, you must use altcoin targeted hardware. 

Brexit do not have any affect on Bitcoin, because largest BTC user group come from USA. BTC price change come from BTC mining difficulty. 

If you know, how to adjust it, then yes - you can make good profit. 

I do not think, that PayPal is popular. Yes, there are a lot of sites, which use PayPal as a payment option, but I do not think, there are people, which use it. Bitcoin is more popular. 

There are not such a places, where you can make a lot of BTC, only in gambling or in Forex binary. Of course in gambling, you can also loose fast too. 

It will survive, but what will be the ETH market value then. Very low, I think. ETH did fantastic bubble and nothing more 

Fear can be for GBP with Brexit, not for gold. What Brexit will do with GBP, we willl see in the future. Gold always have some value in all countries. 

Because BTC mining difficulty going up each day. What else you can expect from mining, which probably even do not have own mining farm ?

Most probably will be scam one day. They have nice site, everything is fine, but unfortunately - I do not see clear evidences of the mining farm. 

One of best profit currently in the altcoin market. The question is when to sale - now or wait some time ?

In gambling only knowledge is most important thing, then you need some balance and only then luck.
