20k$ dumped to 6K$ was difficult but happened, 6k$ to 500$ is very easy soon will be worthless, So Why Some People Dont Believe BTC is SCAM?
Bitcoin reached $20k briefly and then dropped to around $15k. Where was only few days. From there went to $6k in few weeks. That was not difficult, but quiet easy and fast. That was also quite normal and expected. That is like x3 fall.
Now you want it to go from $6k to $500? A 12 times drop. Now that we already had a x3 drop? That is not expected anymore. That would be quite irregular. Such thing could only happen with some fatal flaw in a Bitcoin protocol. I give it less then a 1% for that to happen and for that to happen in next year way less then a 0.1%.
But Bitcoin is not a scam or is a scam because of price. That has nothing to do with being one at all. I suggest you to search for reasons elsewhere.
