That is what I observe too, altcoins is very far from the value of bitcoin right now. No one knows which of them will survive in the long term. If you know you can make a profit now either bitcoin or in other coins then go, if you don't, you will missed the opportunity that may not come back anymore.
Of course bitcoin is a long term player and it will survive in long term and we cannot compare bitcoins to any altcoins as bitcoin is huge and holds a huge market cap in compare to altcoins and investing in altcoins is risky as there are many shit coins available that may disappear with an blink of an eye.
