I think you should spend 25 percent to buy bitcoin ,25percent to ethereum, 25percent to buy other cryptocurrency and 25percent to buy a very good ICO.
Yes, I agree with you on the choices and percentage at which you split the money and this are very potential and valuable coin to have but before you invest in altcoins, I will suggest you take you take your time to do a very good research of the coins and invest in the one you find very promising.
