The cryptocurrency market has been experiencing significant fluctuations in June due to the Bitcoin Halving event and Ether ETF approval. Bitcoin's price has remained inconsistent for over a month, leading investors to look for alternative options. Here are five affordable cryptocurrencies that could offer considerable returns:

1. Flow (FLOW)

Flow is a proof-of-stake blockchain designed for the open metaverse and Web3. It supports consumer-scale DApps, DeFi, DAO, NFTs, and PFP projects. The platform's native coin, FLOW, has various essential purposes within the ecosystem, including staking, paying transaction fees, and participating in network governance. The rising number of users and dApps on the platform increases the demand for FLOW, influencing its price.

FLOW has experienced an apparent upsurge, trading above $0.5846, up over 8%. The token's value has been rising steadily today, with more support in the short and long term for the coin. The market is recovering, which might play a significant role in nudging FLOW's value upward.

2. Hedera (HBAR)

Hedera has initiated strategies to modularize its services, making development, scalability, updates, and problem-solving easier. The team is also updating its network infrastructure to strengthen its reliability and robustness. HBAR's value rebounded from the $0.072 critical support level, demonstrating intense buying interest from the bulls.

HBAR is currently trading at $0.08456, increasing over 6% in the last 24 hours. The token is gliding around the ascending uptrend line, resulting in strong acceptance. If the bulls sustain the price above the 50-day SMA of $0.083 and manage to smash through any descending trend line, the token might rise to $0.095.

3. Polygon (MATIC)

Polygon has integrated an AI data layer into its protocol, enabling projects on Polygon PoS to make data-driven decisions. The team offers polygon builders a free trial for comprehensive user engagement and analytics. MATIC's price, currently trading close to the $0.60 mark, displays signs of a possible explosion in value.

If Polygon manages to overcome the critical resistance point of $0.6, it could surge into the $0.69 to $0.77 range, giving a significant ROI to investors. Numerous critical indicators imply a potential uptick for MATIC. The RSI is in a bullish zone and hovers above the overbought zone, indicating that although crypto market sentiment remains negative, there could be room for more price increases for Polygon.

4. Mega Dice (DICE)

Mega Dice is an established casino aiming to transform GameFi. The token rewards current users and attracts new ones, playing a crucial role in Mega Dice's gamification plan. The project has raised over $1.5 million, indicating significant interest in this novel concept.

Each $DICE token is priced at $0.075. Those interested can link their wallets and swap SOL, ETH, or BNB for $DICE tokens. Mega Dice has sold over 21 million worth of $DICE to date. The project ensures that the presale is inclusive, and post-presale, they aim to list $DICE tokens on decentralized exchanges (DEXs), potentially enhancing their popularity.

5. Gala (GALA)

Gala allows developers to create custom tokens, smart contracts, and node networks. The project facilitates bridging assets to other blockchains like Ethereum and Binance Smart Chain. GalaChain, a layer-1 blockchain, drives the Web3 ecosystem, initially tailored to the Gala's entertainment ecosystem.

Gala's security is endorsed by CertiK, ranking it as the most secure altcoin globally. Utilizing a Gnosis multisig safe, Gala ensures collective oversight and operational security. It collaborates with esteemed agencies to maintain governance and compliance standards.

Gala is currently priced at $0.02932, having surged by 5.83% over the previous month and experienced a 47% increase over the past year. It exhibits strong growth by trading significantly above its 200-day SMA at $0.024292.
