You start by reading Attack of the 50ft Blockchain, and decide not to touch it with a bargepole.

What you've got with Bitcoin is a small number of people with a significant number of them. It will never be a widely adopted currency: by design Bitcoin can't handle enough transactions. It would hurt the interests of the 'miners' - those doing the equivalent of solving Soduku puzzles in exchange for more Bitcoin - to do more. As they're having to pay for enough electricity to power Belgium to do that 'mining', this isn't going to change.

You accept some at noon and by 2pm or so, you can be reasonably sure they're yours. (Before then it's possible that the system will have decided that they're not.) The speculation around the price, and the ability for the big boys to manipulate that, mean that your £100 of Bitcoin could be worth £90 by then.

So they're no use to anyone and the trading price is only held up by imaginary money ('Tethers', another crypto that no-one seriously believes is worth what it claims, but Bitcoin big boys have to pretend actually is...) so they need some suckers with real money to sell them to. Don't be that sucker.

The other major player is Ethereum. Again, it will never be a useful currency, but it's great for losing money via assorted scams or general incompetence.

Everything else is an 'altcoin' (polite name) or 'shitcoin' (reality). Someone will make money off them, but it won't be you: it'll be the founders or a hacker.

Whenever someone offers to pay in anything other than cash and tells you it's worth £x, the question to always ask yourself is "If I had £x, would I buy this thing with it?"

If/when the answer is "no", don't accept it.

If it really is worth £x, they can sell it for that and bring you the cash.

You might have seen 'Bitcoin worth $30,000 each!!' stories today.

When I looked, there are currently around 18,587,306.25 Bitcoins in existence.

(The number of them goes up by 6.25 every ten minutes - at a cost of only around 72,000 GigaWatts of electricity each. In comparison, London uses about 40,000 GigaWatts in a year.)

When someone sold 150 Bitcoin for actual dollars yesterday, the price fell by $3,000.

Selling 0.0008% of the supply of Bitcoins crashed the price by 10%.

Conclusion: the amount of actual money in the Bitcoin system is so low, their real worth is almost nothing. If you have any, sell sell sell.

_{(Not financial advice; I thought Bitcoin was a stupid idea when they were worth much less than a dollar. Nothing since has changed my mind.)}

The price (that you can't get if you want to sell more than a tiny bit) has been going higher recently. That's because the collapse is coming - a combination of a court case that will expose the Tether fraud and the US insisting on 'if you want to be a currency, you have to follow the rules real currencies do' soon - and the big boys with them need to get victims' real money before the music stops.

The proven way to do that is to manipulate the price upwards to attract victims on the basis of FOMO, drop it via selling your own Bitcoin to them for real money, and repeat.

In terms of its use for micro-transactions, someone was charged a fee of $82,000 to move $1.18 in Bitcoin recently. It was probably money laundering (concealing who controlled what Bitcoin) or some other illegitimate transaction in that case, but..

My question tho ,, Can you mention on AW that you are accepting cryptocurrency payments from clients ? “

Yes, of course you can mention what payments you will accept. Just add a note on your profile, in the FAQs section or both.
