I don't think so.

As the development of the Cryptocurrency and more and more people start to take part in field, so the exchanges will get more competitions,and exchanges will try their best to lower the fee of the transaction to attract more people into their caves. It is normal and certain development from a new industry to more mature market. More will be cheaper. Better tech will bring better life to the people based on the help of the government. For example, BitOffer exchange is featured with 0-fee and 0-margin. Recently. They even lauched the funds with capital and interest-guaranteed.

As to mining gas, because they can be more efficient with the better high tech. You can earn more totally from more people.

From the trend of the chart, I think the high was being adjusted, it tended to callback.
Do you think there will be a big plunge tomorrow?
From the view of the market Bitcoin deriveratives, many exchanges like BitOffer, Binance, Huobi, started to launch the Bitcoin funds to cater to the market. it is because they guess Bitcoin will not keep peace in uptrend this time and many people will lose way in the bitcoin change and they catched the market pain points also.
So I think the rest of this year, the funds investment with relatively fixed interest and even capital and interest guaranteed, will be popular.
What do you think?

20% interest per year? are you sure? So you will charge higher fee than other exchanges, right?

My heart for the bitcoin is dead. Don't persuade me. Waiting for the comment about the BitOffer QA wealth management. If it provides stable return, maybe I will come back to bitcoin investment.   

I agree with you. I am looking for the wealth management product which is better to be 0 risk.

BitOffer QA Wealth Management “DEF Win No.1” will be launched on Oct, 22nd:
QA Wealth Management is the first cryptocurrency BTC assets management that guarantees capital and interest. No Risk at all.
It features by fixed 20% Annualized Rate in USDT, being able to purchase and redeem anytime,100 USDT starting to purchase.
Don't miss.

How to hedge for future loss?

Keep to buy options whether you buy long or short for future.
For example,
The price of Bitcoin is $10,000
1.you invest $500 to buy longs with 20 times leverage
2.At the same time, buy 2 put options(cost $60 ) on bitoffer exchange
Option period: 4hours
1 option profit =1BTC spot profit

After 4hours, there will be 2 results.
1.Bitcoin rose by $200, change is 2%
Future: spent $5,00 and earned $200
Option: spent $60 and lost $60
So the net profit is 200-60=$140

2 .Bitcoin dropped by $200, change is 2%
Future: spent $5,00 and lost $200
Option: spent $60 and earned $400
So the net profit is 400-200-60=$140
