Belarus is still a dictatorship with strong ties to Russia, so entrepreneurs and investors will be very careful around it. There's no guarantee that tomorrow Lukashenko won't turn 180 (either on his own whim, or because Putin said so) and ban crypto and mining. Investors prefer countries with rule of the law, because they are much more predictable than authoritarian countries.
This want worries me though, they are talking about BelNPP (Belarusian Nuclear Power Plant), I don't know I might be paranoid or what but part of me says that they maybe masking from behind by using Nuclear Power Plant. Maybe the dictator can used it to gain wealth quickly or more sinister motive, so I have mix emotions about it.
