Bitcoin is not the safest but the most stable cryptocurrency in terms of its place and also the market capitalization of bitcoin. Putting money in bitcoin and waiting for at least 3 years is a good timeframe to wait if you want some serious return but for me, it is better to use it for trading so you can multiply it on how much you want by just doing trading and not only waiting for the value to go up.
Why would bitcoin not be the safest coin out there?
Any arguments for that?
The technology behind the blockchain is proven to work and all it needs to take of is user base and merchants adoption.
Bitcoin has both. Some coins manage to have 1% of the second. But they will never ever threat bitcoin in terms of spots you can actually use it.
And some managed to have a huge number of fans but their moment of glory ended, see doge for example.
Bitcoin is more safe than any other Crypto currency in the market. You cant compare it with any other currency, because it has the largest community, and the highest price so far. I havent seen any other crypto currency in the market that is up to $500 but Bitcoin is more than $4000.
