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.
Yes bitcoin is always ahead in the price or popularity or potential. thats all people are greedy at the back of bitcoins. Always like dodge, dash, ltc are some quite low to use by people.
