check out TradingView, i know it has bitcoin and i have seen some people link some of the altcoins where they did some analysis on.
https://www.tradingview.com/s/bitcoin/The best way to find the technical Analysis for crypto is Bitcointalk "Technical Support" Forum.
here is what it says below "technical support" board:
"Questions regarding issues with Bitcoin Core, nodes, the Bitcoin network, transactions, and addresses."
do you see any remote connection between any of that with "Technical Analysis"[1]?
