Bro he is asking about trading information which can be used to bump the trade value in the trading site.
If you want to know who is bumping the bitcoin price or other altcoins. You should understand technology and updation in it is thing bumping the bitcoin price grows and if you find any issue is bitcoin or hark fork in it. it will face the dumps in the chart.
I don't think so. OP said: "Please suggest me some free/paid pump groups." If he wanted information, then he/she can read cryptocurrency-related news articles for free online. OP specifically asked for groups.
If ever OP really is looking for information sources:
