Even if the bitcoin price was so high its still be a better choice to invest with it so that you could have a huge profit the future.
But it also good if you choose an altcoin that you are trusting to invest with.
Its much better if you have a variety of investment,
Dont just focus on one coin.
Because if ever the bitcoin fall down you still have a back up altcoin that will bring you a profit and vice versa.
