Ethereum is going to be left behind by Cardano and Eos because of it's poor scalability so I won't buy that one but bitcoin will always be in my picks.
Are you shilling for EOS and Cardano, rather than say about the thing that doesn't make sense and you may better to learn more about the hardfork. Even bitcoin try to fix its scalability through the hardfork. 
Scalability can be fixed anytime the problem is to minimize the risk in the hardfork itself.
You can buy bitcoin as much as you can.
