I think the market of alt coins depends on Bitcoin for now, and I suspect that in the next few months when Nvidia releases the new graphics card (March-May timeframe) it will have a huge spike again.
Only this dependence is not quite clear!When bitcoin grows in price,altcoins are falling!And it's understandable,everyone sells altcoyins that would buy BTC!But even with the drop in the cost of bitcoin,the Altkoins remain in the drawdown!
