I'm going to pick out this sentence in particular. Bitcoin used to be a hope for me as an alternative currency. But today I see Bitcoin more as a commodity (digital gold) and no longer as a currency. Instead, the transaction costs are much higher, which is inefficient for any payment process, especially for small commercial amounts. And if you look at the development of the last few years, there is little hope that there will be further developments that will significantly reduce transaction costs. I would rather see coins like Litecoin or Doge as a currency because they are more practical to use.
