I believe people will be able to make more money with altcoins investment compared to what they do get from bitcoin investments this year.
Agreed.Just as people lost more money hodling alts in 2018 (because they lost value faster), they will have more gains keeping alts (because they will grow with BTC in 2019).
But I personally don't expect any ATHs in 2019, not BTC, not alts. The market will recover sometime in 2019, but not to the full ATH. That one will take a bit longer.
