Can I return to the market and invest in it. If you, how do you choose?
You can and why not? you can also take a chance to participate in the sale of a new project. I know top 7 icos and that was a legit source to get the hottest ico.
BTW, I have got $129k in this bull market, can I make more?

You have been getting a very big profit from this bullish market and why don't you just try to take a small amount from your profit and then invest it again in the legit project. There will always be opportunity in the crypto market.
