i own a load of ALTCOINS .many that are not ETH compatable , non ERC 20 based ( i dont know with some of them if they are or not)how can i store them safely off the exchanges ? i have a ledger nano but not sure if this will accept some of these altcoins eg LBRY VOXELS EINSTEINIUM , RADIUM , GAMECREDITS……. etcsome sites have wallets to download , but then takes days to sync and i’m not sure if i can trust them , they look very insubstantial , crappy , ” flimsy ” .i downloaded JAXX wallet , transferred some bitcoin , but then i could not get it out of the bloody thing ! my ether wallet seems works well as does Exodus for the mainstream coins i hold.any help greatly appreciated.thanks Tom.
