Before I used coinbase wallet but i switched to coins.ph which has better GUI, easy to use and offers high security for your account.

Just multiple investment into trusted invesment platform. The more you invest the more profit you will gain . Also engage in trading but you have to make wise planning inorder to gain more profit. There are different ways to earn bitcoin just search it and you will find some  sites offerring btc payment exchange to your service or work

Done!! I think this a part of your school thesis or school research work ?

I thinks bitcoin wallet provider always collect fee whenever we make a transactions like pay outs and conversion of bitcoin to other currency. that is the only way that they can earn profit from their client. Always look for your local bitcoin wallet provider in your place which offer good security and easy to do pay-outs transactions.

Yes , that is common for every one when we are about to buy bitcoin. There's a lot of wary and questions rises in our mind. other worry are  bitcoin wallet security(Tendency to hack my bitcoin wallet address by someone)  and not legit bitcoin seller site.

Its the best time to buy altcoin today since they still cheeper today.,sooner in time the price will go up and you will earn but make sure to review the market first before taking risk.

I thin for me , lets stick to call it bitcoin so that it will not create confusion. Today many people are still have no idea with this currency. just only my thoughts.

Conduct a reading before making a deal. You better examine the system or program that they are offering first . Most scam has poor security features and not commited to protect investors money. Just be vigillant always. Its better to think twice or more before you agree or invest.

In my own view I do suggest Investing your bitcoin to a legitimate and productive investment company so that you will surely earn. You can also try trading but make sure that you are knowledgeable and up to date of  the information like Price, trend, and news everyday and off course you are willing to take the risk in order to earn.

Should I say that most of my colleagues, family, and friends doesn't have idea or information about bitcoin.
there are only few who knows some details about bitcoin and they are not engaging into mining or investing bitcoin at all

You can continue to buy bitcoin as of this moment but be ready for the little profit return ,since the bitcoin experienced down price last month when other country pass a law to shut down the bitcoin,however the price is recovering and I expect to go in peak again in the coming days.

Doing bitcoin work, helps the unemployed to generate income for their personal needs. Its really big help for them to do this business since this kind of sideline is not requiring interview or higher degree of education as long as you are knowledgeable and know how the crypto currency works

For me i prefer online wallet since i used it for a months now. make sure that your E wallet is trusted and has very good security

Holding a bitcoin for a long time is not strategical in some factors because it is quit risky due to the flactuation of the bitcoin price in the market. Almost everyday there's is unexpected up or down of the price trend. I think we need it to invest, sell our bitcoin when the price is high to gain profit and buy a bitcoin when the price is lower but like what i've said it is risky.
