Are there any good predictions for altcoins like ADA CORDANO, POLKA DOT, XRP. in 2021. I've been buying so many of them in November and to be honest I've been so impressed about  the POLKADOT it's growing fast that I was wondering if it's  possible to invest more money on PolkatDot  or just for maybe  just wait for the price to go low again? and how long can we hold those altcoins until get the perfect gain

And anyone can tell me more about BTCST? I've earned that coin on staking BNB on Binance But the problem is that I can't convert  BTCST to any other coin is ts possible de convert it or no ?


Thanks you
