Today I bought COIN.
At first, I placed a limit order at $350 ahead of the opening. However, rather fortunately, it failed to execute. I then manually bought at $325.
I have no clue where the price will go short term. It may drop to $100 (about $20B valuation) or raise beyond the opening price of $381 (about $76B valuation). Anyway, I would not bother investing short term. I should add I do not expect significant dividend income either.
Rather I intend to keep COIN until retirement, about 25 years from now. I am unsure if people will still be making money using cryptocurrencies by then. But hey, Coinbase could be a profitable company even if most of its customers make a loss. Think of betting companies. The thing with cryptocurrencies, once they crash (they will eventually), there is always those that seek the opportunity. There will always be someone paying fees.
