Which it has done numerous times in its short life. Not a big surprise, and not the real source of the country's problems.
What would default mean in this case anyway? The IMF comes in and claims ownership of state resources?
Perhaps making a highly unstable, speculative cryptocurrency legal tender is a bad move then.
Using crypto to buy goods works OK when the price is relatively stable, but as soon as it makes big movement, lots of vendors stop accepting it. Crypto acts more like (and increasingly moves like) stocks, where investors buy in hoping to profit by converting crypto back into cash the same way stocks are sold.
The entire government will have to resign and it will be the end of the great cryptocurrency adoption LMAO.
