Well, I will always recommend btc over altcoins. I am saying this because of the current value of btc in the crypto market. Undisputably, most altcoins are down and securing more might be a better choice but securing btc now is the best in terms of comparing values. BTC is always up there in the market but the altcoin might fail you in the end simply because most altcoins are not doing well in the current crypto market. Some end up fading off at a point in time.
