until now there is no fear that anything will happen with bitcoin, because bitcoin will be quick to correct the movements that occur. I still have faith that altcoin is still very much affected by bitcoin, because after all the existing statistics do not always reflect that altcoin movement is due to improvements in altcoin itself.
altcoin clearly remains as profitable as bitcoin and that also cannot be denied, but until now the movement of bitcoin is very influential of all altcoins that exist, few altcoins can move on the capabilities available to them and are usually only temporary and do not continue to stick.
bitcoin is still a very profitable investment for now and is highly sought after, not underestimating altcoin of course in this case, if you see too many that altcoin can perform well and very promising. but it does need continuous analysis of altcoin which we will make an investment of course.
