I like loyalty programs in various services. In the online exchange SBERBIT, it's quite easy to exchange money, and over time, you earn a discount for it. It consists of 5 levels, and upon reaching a certain threshold, the exchange rate becomes more favorable. Although the increase is insignificant, it's still better than nothing. Considering this, sometimes exchanging money here is more profitable than in other places. Right now, I have a 0.3% discount since I've already exchanged $1.54. The dollar peg is a common practice. There's still a long way to go until the next discount, which, by the way, will be the last one – the threshold is $5,000, and the increase in discount is minimal: it will be 0.4%. All the exchanges I've conducted took only a few minutes. The rate is almost always good. This online exchange has a positive reputation on monitoring sites, where I learned about it. It's hard to find something more profitable for exchanging BTC.
