Which is better: Invest my Bitcoin on legit mining sites and purchased power before the halving because it is currently cheap or save my bitcoin and trade it after the halving because its value might be doubled?
Its best to stay away from these mining sites. Its better to sit on your coins for now. You could trade a few times which is what i personally am doing
Yeah those sites are cloud mining site and there is no cloud mining site are legit they are not all paying. just like investment site .
So in my opinion better to dont spend it or invest it there..
