Yeah...I have BSV and BCH on legacy wallets...I should soon move that stuff off..pay the cap gains and put it into BTC Core...I have little hope for either of them.
I am also thinking the same to sell off if the price rallies again and convert them to bitcoin and wait for the huge rally, considering the way in which the speculation market moves i do not mind which one is giving me the maximum profit as all the coins in the market goes through the same bubble and hence you cannot blame any particular coin for the bubble, we see huge bubble in bitcoin when the market rises and as investors we do not mind in having the profit and so is the case with the rest of the coins, but as an investor you need to be aware of the potential of the coin before investing and not jump into any coin thinking it can give you the profit.
Even the BCH and BSV bag holders don't believe the true Satoshi vision and they have bought the mentioned coins for converting the profit to BTC. In another word, the small pumps on such coins mean the BTC airdrop in their wallet. The chasing pump is the old habit of inexperienced investors and they usually fail to the market whales.
