Skyrocketing Bitcoin Fees Hit Carders in Wallet — Krebs on Security
“We have to take additionally a ‘Deposit fee’ from all users who deposit in Bitcoins. This is the amount we spent on transferring your funds to our suppliers. To compensate your costs, we are going to reduce our prices, including credit cards for all users and offer you the better bitcoin exchange rate.”

“The amount of the Deposit Fee depends on the load on the Bitcoin network. However, it stays the same regardless of the amount deposited. Deposits of 10$ and 1000$ attract the same deposit fee.”

“If the Bitcoin price continues increasing, this business is not going to be profitable for us anymore because all our revenue is going to be spent on the Bitcoin fees. We are no longer in possession of additional funds to improve the store.”

The Polarizing Effects of Online Partisan Criticism: Evidence from Two ExperimentsThe International Journal of Press/Politics - Elizabeth Suhay, Emily Bello-Pardo, Brianna Maurer, 2017
Affective and social political polarization—a dislike of political opponents and a desire to avoid their company—are increasingly salient and pervasive features of politics in many Western democracies, particularly the United States. One contributor to these related phenomena may be increasing exposure to online political disagreements in which ordinary citizens criticize, and sometimes explicitly demean, opponents. This article presents two experimental studies that assessed whether U.S. partisans’ attitudes became more prejudiced in favor of the in-party after exposure to online partisan criticism. In the first study, we draw on an online convenience sample to establish that partisan criticism that derogates political opponents increases affective polarization. In the second, we replicate these findings with a quasi-representative sample and extend the pattern of findings to social polarization. We conclude that online partisan criticism likely has contributed to rising affective and social polarization in recent years between Democrats and Republicans in the United States, and perhaps between partisan and ideological group members in other developed democracies as well. We close by discussing the troubling implications of these findings in light of continuing attempts by autocratic regimes and other actors to influence democratic elections via false identities on social media.
