So here's a somewhat silly but worth pondering question. Stellar Lumens is hyped on Keybase, BAT (ETH-based) is hyped on Brave Browser, and SLP (BCH-based) is hyped on Memo.
The wishful thinking for me is to be able to store BAT in my Memo account. As for XLM, maybe there would be a proxy token? Likewise, to store BCH SLP on XLM & ETH, and so on…
