350 to 700 isn't a massive gain in crypto, but once and if TRX reverses at 360/350, it will typically see good and tends to follow a reliable pattern following channels and fibonacci levels. Which makes it an interesting and safe target for swing and scalp traders.
TRX remains an interesting and highly controversial coin and business, no matter the status of its technology it has shown ability to create business and hype and looks set to do well if BTC has found bottom.
This is a good time to buy TRX but with the current volatility in BTC there is a real chance that if BTC were to correct downwards strongly, TRX will follow and break below the current low on the daily/weekly. So: potentially a great trade but keep those stop losses close.
