If i hve 1btc assets then i would be like short time hold but less amount i will like to choice long time hold and definitely top altcoins.i will buy dip price of some top altcoins then waiting next bear market for big profits. Although short and long every investment palan is risky if you can't find out good coin so be carefully.
If you already have BTC, why should you choose another token to make long-term investments? because holding BTC long-term can also get high benefits than holding other tokens that are not clear, I prefer to keep holding BTC because long and short we can still do it.
