I would like that all of us who do not have bitcoins, should buy $200 worth of bitcoins, keep it in some wallet and forget it. In five to ten years time you will thank me about this investment. Maybe most of the people will have their good retirement life if they just invest $200 worth of bitcoin today.
I'm pro-Bitcoin, but I really don't like the idea of buying at the ATH. It's a very risky thing to do, it goes against investing 101, and it's very likely to end badly. Taking the history of BTC price changes into account, I really doubt the price is not going to drop at least 30% eventually, and I think that a 50-60% drop is very realistic. And then it will be the Bitcoin FUD all over again with people feeling like they missed their chance and reluctant to buy at $10k. Then this $200 idea might be a good one.
I have some limited BTC which I don't sell and kind of always have in my wallet, so I'll just keep doing that.
