"Trading" Term is basically meant for stock market which means buying and selling of shares in 1 working day, which lead to low commission and require the least investment with high trading exposure. But In BTC, transaction fee is same throughout the period. So in BTC market, trading can be defined as one complete cycle of buying and selling of BTC whereas Investment means half clycle. Eg buying 1 BTC means, you invested in BTC and when you sell those BTC it will be called trading.

Ripple do have some resembling feature as you stated here. But the question is IF such bank is formed....Who will be Administrating/manage this bank? Being decentralized nobody can control or regulate BTC transactions, So if there is no control there is to guarantee of re[payment of loans.

I don't think there would totally cashless society for at least 2050. A lot of people who are still not aware of banking facilities and don't know how to use these banking services. Backward countries don't have internet facilities so being cashless is totally meaningless for them.
Cashless and BITCOIN are a totally different concept as one is centralized and other is decentralized. People are using BTC not just being digital but due to features like the privacy of transaction.

In recent times, there are lot ICO scams. There are no guidelines/regulation that an ICO needs to bind before its launch so there is no guarantee of your money invested in ICO. So many countries like China/USA has banned ICO in order to protect their citizen's financial interest.

I don't think mining would be a good idea as the hash rate in mining BTC is quite high and it needs more than 1000 bucks to invest to get a reasonable return on your investment. So Best way is to buy and trade BTC or Etherium to get best return for your investment.

You can earn BTC without taking any risk from the services given in Bitcointalk.com. You can participate in Signature Campaign, Bounties, Social Media Campaign, blog writing services, Making You tube videos etc and other Services ( like Photoshop, Manager, signature design etc).
This is the safest and easy way to earn a good amt. BTC

If China legalizes BTC with some regulation, it would definitely be a beneficial call for all BTC users in the long term as there is no fear of being banned. But I don't understand the process they are adopting, it means User in China first have to buy coin X made by the Bank of China, then convert into BTC through exchanges. That means first user will pay fees to buy COIN X then again pay fees to transfer Coin X to exchange and in last fees need to be paid to buy BTC...that is 3x fees to buy and 3x to sell. This plan only is efficient if transaction fees of COIN X  would be negligible.

I don't think any wallet will pay you interest on keeping the BTC in their wallet. Instead, they might charge something to give you wallet service. You are not lending them BTC, You are just keeping it and you got all the rights to withdraw all BTC anytime.

I don't think any common man is against BTC. It is the central authorities which creates a propaganda against it. I think there are only 2 kinds of person who are against BTC transaction:
1. Administrators of central authorities or Political Leaders as they think that BTC could snatch power from them.
2. People who are not much Technological friendly and don't know how to operate gadgets like PCs and smartphones.

To change the habit from cash to digital money would not be an easy task. There is always a challenge to teach about BTC or Fiat digital currency to illiterate persons or blind or poor who don't know how to use smartphone and internet. Being totally cashless is not possible in near future.

ICO and Token are one and same thing. You will get tokens in ICO sale. Initial coin offering(ICO) launched by a co. to raise crowdfunding from the public all around the world. It helps entrepreneurs to raise funding for their project. If ICO get overwhelm response than its price increases otherwise will get decrease.

Technological unaware/unfriendly folks have never heard about it. Even if they have been told by someone, they will not believe in this thing. I discussed about BTC with one of my Uncle, he refuses to believe with the fact that people all around the world are making transactions with a currency which is not authorized by any of the govt in the world and whose legal status is not clear yet.

Growing popularity and acceptance of BTC among the people all around the globe make it so-called GLOBAL CURRENCY. But I think it should be called the INTERNET OFFICIAL CURRENCY coz it being digital in form, it could be accessed through internet only. People who are technological unaware has never heard about such currency.

BTC has created more employment. It created more job opportunities for software developers, designers, and other IT professionals. Moreover, it also boosted start-up business as it created ease in raising funding at the global level.

ICO with a product is more safer to invest as compare to ICO without product. These ICO's has already completed a major part of their roadmap. Revenue generation would be swift and hence changes of growing token prices would be far more than other ICO's.

Nothing to worry about. Altcoin market is going down because of the launch of BTC hard folk on 25oct. Investors are shifting their money from altcoins to BTC to take advantage of this. But soon after BGF launch, investors will again shift on the Altcoins and ICO's to gain more profits.

I don't think it will work. Countries with weak economy also have poor education ratio, poor infrastructure and lack of technology awareness. This will resist their citizens to adopt the BITCOIN as their official currency.
Moreover, BTC transactions are decentralized, so govt lost their control over the economy and no govt want this to happen.

There are  expects to this:
1. It can ruin a nation. As there no proof of transaction so no tax, illegal activities like drug abuse and terrorism will increase. And Govt can't help us as they are short of fund.
2. BTC can be used as a mode of investment. New Crypto-coins help entrepreneurs to acquire funding from all over the world. This will create more employment and built a strong economy.

If you make a transaction in BTC; It does not impose any tax until you convert into fiat currency of your country through an authorized exchange. Tax evasion is a very serious issue. Tax would be induced on Capital gain above the original principal amount invested.

I don't believe it. It means BTC would be accepted everywhere grocery store, hospitals within 15 years which seem to be impossible at this point of time. and for that, it needs govt approval and awareness among common citizens.
