re: Please click on the Home icon to view an intro page. Do not worry about acumulating testnet coins, it is not necessary a big amount to test the basic concepts. Focus on knowing the different kinds of cryptos: digital coins, smart contracts, DeFi, Oracles. Learn to use wallets. Claim some cryptos (btc, ltc, bch) to test transfers; (eth, eos, tron) for testing Dapps and smart contracts; claim some stable coins (usdt, usdc, dai) for testing DeFi in Aave.
