If bitcoin hits $10000 that means that any coin can reach a very good result.
So if you have any other coins, just keep them and wait and you will earn more bitcoin.
Just remember, there is no coin that can compete with bitcoin. BTC is the main currency, but if you bought any other currency with low price and you have a good amount of it, do not rush to sell it if you have no profit. Just wait, be patient. There are some people who waited a few months to sell and gain the profit and they are happy now.
For example I waited for Cardano (ADA) for more than one month to sell it and today it's doubled, so I sold it and I'm happy that I have more bitcoin than ever before.
