Market is witnessing some gradual dumps and it's a know fact that altcoins will bleed more than bitcoin and they will be stable or recover only when bitcoin recovers and pumps. So will it be wise to hold on to Altcoin or switch to Bitcoin or convert the funds into stablecoins and wait for market to either start recovering or to dump further to buy more in order to reach breakthrough for the lose which we might have incurred till now.
The bold part is everything you need to know when making your decision. It's logical bitcoin is the best alternative since it's well known the market is only going to recover as a whole when bitcoin recovers itself. Without a strong and pumping bitcoin there isn't profit through altcoins as well. When you hold bitcoin you have the assurance sooner or later it will rise again, but when you hold an altcoin you never know if it's going to increase in value once more, because although there is a chance it's going to be influenced by bitcoin price during a future bull run, it's not a guarantee at all. In crypto market bitcoin is a safe bet, so of course it's better to stick with it.
