Of course everyone who is doing trading course would like to earn more profit every one would definitely buy altcoin with btc. I think with a high bitcoin value this is a reason for traders doing that. besides the usual thing I do is always save some btc I have for a long period of time this I do because I am quite aware that it is true bitcoin is a form of investment that is very good for now when compared with investment altcoin. not to mention the current interest of more and more investors for investment dibitcoin this course will continue to pump the value of bitcoin.
