Do you use bitcoins?

A sub-title here.

In the previous post I said what everybody says: never play with money you cannot afford to lose.
How much money can you afford to lose?

Well, one month's salary or maximum two months'.  It may take you one year to recuperate that amount from a salary.

Losing a 6-month salary is a disaster for many men these days and the chance of fully recuperating the loss is diminished a lot by the possibility of losing the job before all the lost money is saved again.

Playing investment "games" is not for everybody and should not be for everybody.

For my opinion of how cyber-trading, whether securities or Bitcoins, should be approached, read my thread at https://www.expat.com/forum/viewtopic.php?id=337645

Like always, there are those few ones who do and there are many more of those who just sit and watch ... 

Dr Garry Bonsall, Basels English dentist, is the first dentist in Switzerland to accept Bitcoin, the global crypto-currency."I also take WIR, (CHW) Switzerland's second official currency," says Garry, "So accepting Bitcoin from patients for their dental care was a natural and logical step"

Can you please not mind to explain us taking bitcoins in place of currency is how useful in long run.............

No, If you invest and lose all your investment you lose 100%.
