As a member of the forum it's better to visit, to check and engage here to attract others to promote their project in altscoinstalks, because if the forum has no activity who likes to use it. I've been away for a while but when I look back I should not stop of what I am doing for the crypto community.

If you are confident with the project and the tokens has the potential to grow in future hod it, but if not it's better to sell it rather than watching it dies and stuck in your wallet. It's your decision all or nothing.

We can not generalize that they are useless, some projects just become dead because of lack of support from the community. They might have a good idea from the very beginning but they are lack of resources to execute it and the others just waiting for perfect timing .

I don't consider it is a scam, they don't ask for funds, so nothing  funds involved, except  your valuable time. We can not blame them, it just they don't succeed, crypto was booming and unfortunately it goes to south. Maybe in future, they will unlock your funds and you will be rewarded with your patient.

I am still holding all my earn coins too, even some of them are worthless, I made a few mistakes of not selling them during the all high but it was all my fault because I let my greed control over me.  When it comes to your hacking experience to avoid it in future, bookmarked all the pages that you are constantly using and double check them.

If Bitcoin will become very successful in the future. I am pretty sure he will be a fan of Bitcoin. But, I noticed when famous personality  put a remark about Bitcoin, it could boost only BTC prices.

I've been in the crypto market  for a very long time , so I want to invest both it depends on the percentage of my investment because crypto  is very unpredictable and full of surprises. Diversification is a must and I believe Eth and Bitcoin are glitters and gold.
