the bitcoin transaction fees are not high at all. in fact they are the lowest possible. I just made a 1 satoshi/byte transaction and another with 0.4 satoshi/byte and they both got confirmed within 2 blocks.
This fee is considered as a very low for me and also the confirmation is quite fast as well.
However as a passive gambler I need to play a lot so I decided to convert my alts into btc and play but then the fees is a pain in the bum.
If I were you I will not convert altcoins to BTC instead play with altcoins because if BTC goes up soon or later all these good altcoins also will rally because these coins also corrected a lot already.
I'm not a regular gambler. But sometimes I play a dice game and use BTC if fees are less and use altcoin only if BTC fee is high and taking a lot of time to confirm a transaction.
