Very conflicted on this one as I think you either did not own bitcoins from the start and John scammed you pretty bad or this story is made up because what the hell, why would you trust a random person living far away from you to make a financial decision for you?

There’s no government authority that controls Bitcoin, which is the main reason behind its transparency. Decentralised Finance (De-Fi) provides plenty of advantages to investors and customers by eliminating central oversight and unnecessary intermediaries which reduces the overall transaction costs and time. Businesses should accept Bitcoin payments to avail these benefits of De-Fi.

Bitcoin is based on blockchain technology, which is one of the most advanced and secured technologies now. The core design of blockchain comprises cryptographic technology, which is hard to hack. Therefore, I think that Bitcoins are safe from cyber attacks.

New traders must practice their trading strategies on their demo account before using them in the live market. This way, they can save their money from losing and can also get an idea of how their strategy will work in the live market.

What broker would you suggest, and leverage ratio to use?

Singapore is one of the favourites among the crypto enthusiasts as the government is very open to decentralised currencies . The financial laws are very business friendly unlike many other countries and that's why most of the cryptocurrency businesses are getting set up over there.

It does not make it more secure but of course it would make it difficult for the hacker.

Bitcoin is not distributed by one source. Its nodes are spread across in a diversified manner and it does not have a centralized authority or a database.

If influential people buy and sell bitcoin to and fro, it would keep up the hype of the coin. Also, the currency may become even more volatile than it already is due to price fluctuation of this extent. But, it can work out to be beneficial because this will surely create hype among investors.

It's natural that if something gains value or interest then the risk and critics surrounding it increases too. Same goes for bitcoins.

How people portray cryptocurrencies like bitcoins depends upon their own level of understanding. Some think they will replace the fiat currency very soon while others think they won’t even last in the next few decades. It all depends on the person and his understanding.

@kingsden, it's an ever changing economic world my friend. We can trust anything for 100% or be certain of such fiat banks and BTC’s.

Not having a clear plan for my trading is the big mistake that I made in my early days. Actually, having a plan for our investment will help to avoid overtrading or undertrading without realizing the risks.

Among the above listed, I have used macd, RSI and sometimes bollinger. They are good.

The only reason why people are very much into investing in bitcoin is because they think it’s very much profitable and sometimes neglect the losses that can come with it.
