Yes, I think so, but just like a lot of people here would say, when asking about Bitcoin on a 'Bitcoin forum', you should not really expect anything other than positive responses, but tbh, I think every and any time is actually good to buy Bitcoin notwithstanding the price, especially when you're a long time investor as the price will definitely always appreciate back up after correction periods, so if you have plans of holding your Bitcoin for the long period, then buying now is a great idea.
My option for altcoins would always be ethereum, I consider it to be the only altcoin that looks more like a long term project, the thing is, I'm a long term investor so I usually prefer to choose coins that are sustainable for the long period, so having said that, it all depends on the kind of investor making the purchase, if it's a short term investor then smaller pump and dump coins could be an option, it's risky, but it can give returns pretty fast, and can also dump faster.
