Truth be told, in Africa we see bitcoin as an investment rather than as a medium of payment. So, we acquire it and then wait awhile to resell it like a real estate. In Nigeria, I am yet to see any shop accepting Bitcoin for payment. One has to exchange bitcoin first into fiat before any payment for goods and services.

Lately there are many people obsessed with finding Satoshi Nakamoto again and the research that they are doing is getting very detailed in comparison with the research that I have seen from previous years.

Do you think with the improvement of forensic technology and analysis, that it would be possible to find Satoshi Nakamoto in the future?

I am amazed with the research that was done so far and I think we would eventually get very close to Satoshi Nakamoto's real identity. The reason why I say this is based on how DNA technology helped to solve many crimes, after it was developed and used in 1986. Lately they even found Serial murderers based on their genetic link to family members who had their DNA logged on some medical database. 

So please make your prediction and decide if you think that there are a good chance that Satoshi's real identity might be discovered in the future?

Let's discuss. 

Those extortion emails were common several months ago. They included usernames and passwords (that they got from hacked web sites), so they seemed very convincing.

These scammers didn't provide any info to back up their claims, so it's probably just some script kiddies that are just spamming email lists. I would ignore it. Its not worth any more of your time.

Among the popular IEO, Harmony is one. They have been running a bounty program even before the binance partnership and with it getting the lauchpad of binance, the attraction towards it's bounty has highly increased. Though I believe token bounties are a better earning, I prefer quick cash for my work.

If Satoshi wants to stay anonymous he should be allowed to do so. He gave us all these options and freedom with Bitcoin and the least we can do is allowing him the right to live his life in peace

Sales are everywhere. Sale on shoes, bags, shirts, gadgets and everything. Malls and shops use this technique to attract buyers, but you know what?  Do you think you've been discounted a higher price than ordinary? No. Instead of saving 20%, you spend 80% on things you dont really need. This is not economical and most of us are easily lured to it. This is what i hate about people. When there's useless trending items on sale, they buy immediately even on credit cards but if bitcoin drops, they talk negative about it. Normal mindset wants to get temporary attention. Not permanent comfort.

Can hardware wallets like Ledger Nano be hacked and their coins stolen?

Bitcoin is not money.

It is more an artwork with 21,000,000 limited editions. And each limited edition contains 100,000,000 limited pieces. (satoshis)
