If you ask how bad is Altcoin? I think not too bad. Since the beginning of 2019, Altcoin actually slowly grew. But that growth looks very slow because if looking at the price hike Bitcoin is already very high. Looking at this kind of condition I also prefer to focus on Bitcoin trading.
The Altcoin season doesn't come and we have to be patient. I am sure if the season for Altcoins is just waiting for time because until now Bitcoin looks stable.
BTC is always a big brother and the market movements are all related to BTC. Bitcoin has controlled more than 50% of the total cryptocurrency market value recently. This is probably the time you can buy altcoins cheaply and keep them for the long term. Be patient and wait for your opportunity.
