You seem to be French....
Are you sir?

Back to the point. I know the minimalistic withdrawals are not questionnable. Though there's is much data exposed about how reliable this is. There seems always to something. Cause, what is their catch? If its gonna take so much time. A sudden fall in price level would lower the value of Bitcoin in terms of usd. Let us take into consideration that the value of btc we receive will be based on the value of USD so if price fall...we get a lower number of btc. And there is no certainty whether it will remain increasing in terms of rate. The percentage increase would gradually diminish. The mining and obtaining would be difficult. Leading transactions to take months to be executed. Thus, the small value of money we are getting may take too much time. Its like searching for 0.5 dollars to be received in 2-3 months. But let us hope devs find something to ease the usage and every other things.
