We can never tell whether this 2021 will be the same on what happen on that said year where alt season started but I have confidently convinced that it has a very high possibility that alt season is on its way because seeing the market bullish not only for bitcoin but also to several top rank altcoins that made me strongly feel that it will make a new history for crypto world and industry.
Coins just don't go up like that. There needs to be a solid reason. Bitcoin prices have gone up, as a result of the hype surrounding integration into platforms such as PayPal and Square. Some of the altcoins have also gone up, mainly because they are also traded against BTC. Their exchange rate versus BTC has gone down, but that against fiat has gone up. But this trend is not going to last much longer and the hints are already there. Bitcoin dominance now stands at 72%. It was 57% before the start of the bull run.
