lots of people do not want to buy solana anymore because they believe that its peak has passed and if you buy now where the price has increased, it’s never going to pay off
Where are these people who do not want to buy Solana? This is not the ATH for Solana there is current bad news on Solana which is why it keeps declining but I believe it's not the last highest price for Solana.
It's currently having issues or bugs related to transactions and they are planning to fix the issue next week by April 15 it is not only Bitcoin having issues with the network congestion Solana also experienced this too once they fix the issue expect for the price surge.
This is the crypto space and news affects there prices, so you don't expect any crypto coin to have a smooth sail and keeps increasing indefinitely, they're volatile by nature and that's why pump and dump occurs. When it's a reputable altcoin like Solana, we don't need to worry whether it has the potential to surpass it's ATH in this bull run, I believe that when it's dev. team rectifies it's network issues, it'll price will increase. So the OP will have to make that decision whether to still jump on the bandwagon or give it a break.
