Upvoted. Nice one on point.
To butress your points:
Erc20 Ewallet: You need this wallet for token/airdrop withdrawal, recall new altcoin is emerging on a daily basis, hence the need for erc20 wallet. You cannot withdraw tokens to your xapo, coinbase, luno etc account because they are nor erc20 compliant. You need ewallet like imtoken and trustwallet.
Telegram: cryptocurrency has shown to give support to telegram. This due to the fact that it supports block chain techology, broadcasts and the use of bot. To meet expert and also for airdrops, you need a telegram account.
