We had no ICO or Sales at the launch of Bitball & decided to airdrop 200 million tokens for free for decentralisation. After few months we monitored the transactions & realised that huge amount got claimed by fake accounts or accounts that never existed on an exchange. We decided to invest more money and time to carry out a swap of the old tokens to eradicate those fake claimed tokens and verified all the new tokens's circulation. For more information, please check this link: https://www.bitball-btb.com/news/bitball-btb-swap-ebarter-trading-platform-launch-date-1st-july-2019-user-deposit-cutoff-29th-june-2019.
Swapping of old tokens is finished & its not possible to change any other tokens from the old contract.
Conclusion: our recommendation is to follow the exchanges and prices through coinmarketcap, blockfolio & coingecko as they get updated quite frequently.
