better to wait as of now, its price today is high, and bitcoin price will rise soon, and when that happens, altcoins will dump so wait for that moment and grab that opportunity.
Yes, I agree that it is better to wait for now since bitcoin price is currently in a higher value. I suggest not to buy BTC this time. Wait until its price falls down before to buy and then keep it in your wallet and wait for its higher price again and sell it or maybe you could just save it there for future investment.
