Do you think Bitcoin is worth investing in? Is it safe?

No and no.

This exact question was asked a year or so. The answer is the same now as it was then.

Just like buying shares, only touch this if you are an experienced and successful stock-market gambler who has enough money to not mind losing it on a wrong guess about whether the future value of your investment will go up. The fact that stacks of other people have bought into it in the past is not an indication that at any given moment you will make an easy profit - particularly now that when the global economy is so fragile.

No. And no. I don't have enough spare dosh to gamble it away.

You've got to be wealthy in the first place to invest in this way.

I have tried to understand how it works but I simply cannot understand anything about Bitcoin.

How on earth does it function, I haven't a clue. 🤔

Not for me not that I ve got any money to invest but wouldn’t if I had

Don't touch it!

I am risk averse so it’s a no, no from me.

No and No. I think it’s a big con. You might make something if you have lots of money to spare but why take the risk

A big NO from me, too. Stay away!

Only invest an amount that you can afford to lose - I can't afford to lose a penny, so I don't take risks ....

When I signed up they never left me alone, withdrew the money next day

I did when it first appeared ( on my step daughters advise) and made money. I have no idea how it works but she does.
But as someone said: it's a gamble and if you can't afford to loose it, don't gamble.
Having said that: my late father in law was a professional gambler for many years and made a living.

Someone I know invested some money, and last time we spoke, had done very well.

Apparently, you can invest small amounts, it doesn't have to be hundreds.

Gold is your best bet if you're a quick gambler as the price fluctuates daily but looking to the future it's a safe bet.
