Projects that pum & dump & gets abandoned or worse are bad... but it's not always token devs who do it... there are big groups up to 200k members who organize these. Some tokens get pumped & dumped in series, and actually the value rises and rises. So, it's complex question.

Would you invest in well established crypto like Bitcoin / Ethereum or XRP etc., or choose some new project?
I have invested / traded established cryptos long time, but now it seems that there's only moderate profits available with high risk... so, I have changed my strategy, and started to go through new projects even at presale stage, and if I feel comfortable with them, I will buy @ presale. of course it's super-high-risk compared to investing in established coins, but i think also rewards could be very different.

Are you looking for a place for selling your token? Surely Binance Launchpad is the best place to do it. But it may take a little bit expensive in charge to provide it on Binance Launchpad. But it should be sold out only in a few minutes because all people must buy as quick as possible if it is launched in Binance Launchpad. What do you think?

Yes, looking for the place where to arrange presale before DEX listing. Thank you for the idea about Binance, it looks really good and sure potential is the best, but as you said maybe it's also a bit expensive, and process to get project on it seems a bit complex, i.e., may require quite long time.

I'm preparing with my team for a BSC token launch with a presale.
We're currently thinking PinkSale or DXSale, but there's lot of others also.
What is the best launchpad and why? Thx in advance!

Yes, you can do well... if you are lucky. Some projects goes nothing, some can moonshot. I.e., some time is wasted, and some well paid - in long term - meaning you need to do bounty after bounty to have better changes!
