That's a good goal if you are just planning for 'money', but are you sure that altcoins you are buying are not shitcoins?
There's a lot of shitcoins nowadays, so be careful. But I also believe that there are many shitcoins are still making money $$, even they are really a big shitcoin, money still there, so it's ok. What my I want to happen is altcoins should help the Bitcoin for it's problem or even in helping the adoption of Cryptocurrency.
