Bitcoin I have been said and proven to be one of the safest digital assets to invest and hold for a long period of time.
But it’s all left with anyone who want to make an investment to decide which one they want to invest on it’s there money and there personal decision, and just so you know there are altcoins which are consider shitcoins that are worth investing on, not all are completely useless so we can still make few right choices but those are risk which anyone who want to get involved in it are going to take.
Few shitcoins are worth investing on and taking profit when the time is right but they are not meant to be kept and hold for long period of time because as soon as the hype is over the coin will continuously keep losing value.
Of course you are right. I think it is wisest to invest on Bitcoin for the long term. But it should also be understood that there are both good and bad everywhere.
Short traders also lost by investing in Bitcoin. That is their failure.
Now which one you choose is entirely up to you. I will always prefer Bitcoin.
